I’ve only been using it for a couple of days, but for now I’m happy. I had never used trackballs before, and from the first moment it had more precision than I expected. Furthermore, as the days go by, I notice how it becomes more natural. It is quite comfortable for the wrist.

I have used this product for a month so far, it seems very comfortable to use, the battery lasts about a week and a half with the lights on, it can be connected via Bluetooth to a phone without problems, and I am very satisfied with this purchase. I think it is a very good product considering the cost-performance ratio. At first, it feels strange to use, but after a couple of days, it becomes easier. I recommend reading the instructions to adjust the sensitivity to your liking and make the most of it.

Dobrze wykonany wraz z kompletem instrukcji i przewodem do ładowania.Ogòlnie polecam.

muito bom para a mão, bem gostoso de usar, durabilidade bem boa bom dia a todos, pode comprar vale a pena

Professional quality, excellent price / value rate! Thank you

The grip is amazing and it seems that it is more difficult to operate than a conventional mouse.

Well made with a complete set of instructions and a charging cord. I highly recommend it.

Absolutely wonderful trackball, forgot to write a review immediately, but probably all the better. I have been using for six months and enjoy more and more.

Everything is in agreement

Immediate delivery and excellent operation, the ball rotates without any problem and it is easy to adapt to it. Additional buttons work well in Linux.

I didn’t think my Elecom DEFT PRO could be beat – turns out this trackball has it all – ultra-smooth, ultra-quiet, very very nice. Thank you, ProtoArc!

Product arrived as described with timely shipping to the States. The mouse is a delight to use. I appreciate the quiet click of the main and secondary buttons. USBc charging is also nice.

Очень неплохой трекбол, брал чтобы использовать лёжа на диване) Достаточно плавный ход шарика, кнопки бесшумные и с хорошей тактильностью. Недостаток наверное только один – не очень удобно и довольно долго переключать чувствительность сенсора, хотелось бы отдельную кнопку. Подключается по блютус без проблем. так же удобно. что есть возможность подключить через юсб адаптер в комплекте.

Все отличнл, доставка в срок, все работает, Очень доволен)

All ok, fast shipping, good build quality. Arrived before the estimated date and in good condition. It’s not so accurate for graphic design but it works.

love them. I have 3 in use and another 3 for spares. I am using these as a replacement for Logitech marble mouse that I was using for over 25 years they are much the same but are wireless and have a scroll wheel

I received quality and adapted to use. The pain is fine for the price.

I write based on the results of two days of use. Pros: good quality materials and assembly, quiet buttons, flexible settings. Ergonomic shape, fit well in hand. The trackball rotates easily and silently starts does not require much effort. Subjective sensations: it is difficult to wean from an ordinary mouse, a change in motor skills is required. For now I miss when I hover the cursor. Perhaps the trackball itself should have been made heavier to slip less. Result: the product is good both in itself and as the first trackball.

BUENISIMO, MUCHA CALIDAD, MUY BUEN EMPAQUETADO Y CUIDADO. CALIDAD!!!!!

Трекбол просто супер! Работает долго, купил 2 штуки. Проблем нет. Можно смело брать!

Excellent works at the 1000%

good good good

Excellent quality price relationship. The surface feels like a hole which improves the grip. I was surprised that even though the shape is for the right hand, it holds and operates very well with the left.

Works very well, still learning to use it properly after my whole life using only mouse 🙂 Quality is very good for the price of the trackball and I’m looking to many years of usage 🙂 Would recommend to my friends 100%.

Great. Feels like the old school MS trackball

침대에 사용가능한 마우스 찾아보다가 이제품 선택하게 되었는데 매우만족함 마감재질도 뛰어나고 사용하기 편함 블루투스 및 무선연결usb 있어서 확장성도 뛰어남 참고로 침대에서 사용시 볼로 컨트롤 하는거라 첨에 조금 익숙치 않은데 몇번 사용하다 보면 금방 터득함 굿!!!

It was enough a couple of days to get carried away. It is a very well made article, even the material is pleasant to the touch. Although it is prepared for the right hand you can also use with the left hand. Great ++++++++++

Beautiful

Looking for a mouse available for bed, I chose this product, but I am very satisfied with the excellent finish material. It is easy to use Bluetooth and wireless connection USB, so it has excellent scalability. I’m a little used to trolling, but when I use it a few times, it’s good!!!

I have been using trackball mice for some time now and was looking for a new one. I wasn’t aware of the index finger trackball and wanted to give it a try. I am impressed with this product, which looks a bit different than the photo — the body of the mouse is matte finish, which is great. The longer the mouse is used, the less likely it is to end up with a dull finish. The other good thing is the multiple ways to connect it. I also like the fact that it is rechargeable. I can put it on the charger at a time when I won’t be using it so it will be ready for me the next time I’m at my desk. It takes a bit of getting used to, but it’s not as hard as I thought it might be. The mouse is for a larger hand, so I’ve had to adjust my grip a bit since my hands are small.

It’s better than anticipated, and out of the box it’s way better than Elecom Deft Pro (another, well-regarded and popular finger-operated 44-mm trackball) which is three times more expensive and requires ball bearing upgrade. Advantages are: smooth ball operation, the ball never sticks or catches; three wireless connections; four DPI settings. However, there are three disadvantages vs Deft Pro: 1) no wired connection option, USB port is for charging only; 2) soft-touch plastic housing which is a fingerprint magnet and will inevitably degrade and start peeling off; 3) built-in, non-replaceable battery. LED light can be turned off, so it doesn’t count as a disadvantage.

o produto chegou em perfeitas condições, e no tempo previsto, via speedaf

It is perfect, very comfortable and easy to use. Take into account that it is for big hand, for the distance of the button

The product arrived in perfect condition, and in the expected time, via speedaf

Absolutely perfect product, at a competitive price. Both appearance and build quality look really high level. The connection with my PC was instant and without the slightest problem. Product really to recommend.

High quality ball mouse. I bought this and the thumb control version to compare but I prefer the other’s shape. If you want higher level of control with your index vs thumb i’d recommend this.

всё отлично Спасибо!!!

Thank you very well!!!

It is big, comfortable, then I will see its operation But first, I really liked

It arrived quickly, it looks very good, it has weight and looks good quality and the touch is very pleasant. It looks big but I have no problem driving it, for many years I didn’t use a ball mouse and I’m glad to have one again, in my opinion they are the best. The touch is very nice. It works with Linux and the ball doesn’t drag on. We’ve been with him for a week and everything is perfect until now. It has a box and came perfectly wrapped and protected.

Заказал вторую уже, на работу. Всё хорошо, за одним приколом, иногда шарик где-то сторонится, приходится раскручивать усилием, где-то деформация. А так, всем доволен.

good

Exactamente igual a la descripción. se ve de buen material.

llegó en excelente estado, el producto es muy cómodo, para quienes nunca han utilizado este tipo de periférico tal vez les tome 3 días adaptarse, no se frustren lo único que tienen que configurar (presionando 3seg el botón de scroll) es la sensibilidad y con eso queda

Thank you for your arrival on the 9th 3.19 million

Exactly the same as the description. Looks good material.

Excelent mouse. It works perfectly

Fantastic in all respects. Superior quality professional product With an excellent quality price ratio. It was time to stop rubbing the muse on the Mat, with this the wrist always remains stationary. I recommend it to all fans of Computer Desktop.

Perfect!

Great mouse!!! Cheaper casing I’d say but not fragile. This is a great mouse. I’ve put well over 400hrs use on mine and it’s wonderful! Easy to clean and very comfortable.

製品はとてもマットな質感で操作しやすく満足しています。

Muy práctico hasta el momento

gostei do mouse, diferente de todos que já usei, demorei uns dois dias pra me acostumar.

Ergonomika is fantastic, I will repeat the form. The bag to go without rivkiv and easily start. I think about the pidshibniki there are all the same spravna.

Excellent mouse, my adaptation was instant, my hand is fully rested, without feeling any discomfort, my only regret was not having bought before!

Very practical so far

Item arrived in time, matched description. Thanks ——————————————————————————————–

Si no estás acostumbrado a los mouse con track ball costará un poco usarlo, pero sin duda disminuye el trabajo que debe ejercer la mano, se siente bien por el precio que tiene

Excellent product! As published. Can be used in three modes, comes with a manual. His installation was immediately

I’m getting more familiar and comfortable than I thought. I bought it to use in the sofa. The material is very soft and not cheap. The light around the ball is silver, but rather than a Bluetooth connection, it is used as wireless dongle and is recognized right away and works well. I usually only use trackpads without using a mouse, but I’m wondering if I should use one from the company.

Good quality.

Es mejor de lo que esperaba, si es un poco raro pero ya que te acostumbras es lo más cómodo y fácil que vas a usar.

Functional!

Quite a large mouse. Comfortably on her hand. Rustle configuration and connection directly to the computer. A little bit of getting used to working on this mouse. Advantage that you do not need to move the mouse only the ball does the job.

Fast delivery and confirms to the description. Size suitable for medium and large hand

It is better than I expected, if it is a bit strange but since you get used to it it is the most comfortable and easy thing you are going to use.

Good and very efficient mouse, fast and precise, we can compare with much more expensive.

Good quality trackball. The ball slides well in the seat, where there are additional balls. The body material is nice. Tested about a couple of days, conveniently.

Very satisfied! The mouse is a quality product. The delivery was very fast!

llevo 3 días de uso y se siente muy bien. Tarda uno en acostumbrarse pero es muy útil. Las teclas son muy silenciosos

Ottimo materiale, ergonomico. bisogna farci abitudine, in quanto si impugna in maniera diversa rispetto ad altri trachball.

Ótimo mouse, mas ainda preciso me acostumar, pois utilizo o MX Ergo. A loja Seenda Store está de parabéns! O mouse chegou em apenas 9 dias… muito antes do prazo de entrega. Estou muito satisfeito com a compra!

Nicely packed. Looks well made. The ball is little too large. Maybe, it would’ve been better, if the front is sloped more. Yet to get used to it. These are my first impressions.

This mouse feels good to the touch. It doesn’t make any clicking noise. The wireless trackball is accurate and excellent. I’m using Windows, but I feel that the mouse pointer movement speed is a little slow. When I use this mouse on a large monitor or multi-display, the mouse pointer movement speed is a little slow. I’m satisfied.

Good controller. I ‘d make a little more of a button under my thumb, but it’s going to come down like that.

Great mouse, but still need to get used to it, because I use the Ergo MX. The shop seenda store is to be congratulated! The mouse arrived in just 9 days… Long before the delivery time. I am very satisfied with the purchase!

Mouse of excellent quality recommend.

All perfect. It’s already the second one I’ve bought. I have one at home and I bought this one for work. It fits perfectly to hand. Fast shipping and well protected. Totally recommended.
