What about customs?

We are not responsible for any custom fees once the items have shipped. By purchasing our products, you consent that one or more packages may be shipped to you and may get custom fees when they arrive to your country.

For some shipping companies, it takes 2-5 business days for the tracking information to update on the system. If your order was placed more than 5 business days ago and there is still no information on your tracking number, please contact us.

Will my items be sent in one package?

Excellent Product, store attention and store

28 Jan 2021

The goods came intact. Came in a box with a foam. Fully fits the description. The store is sociable, answered my questions quickly enough. True, the goods were detained at customs, received the goods for 2 weeks later. The goods are turned on, everything works... let's see how it shows itself. Seller recommend.

25 Jan 2021

The order was received within 5 days. The courier brought home. Checked, vrodi would work, but there is no instruction in Russian language. Asked the store to send me instruction in Russian language. Now I'll wait.

The device is excellent!!! Took for the mother-in-law, heavy form of the cowboy-more than 90% lesions, 2 months in the hospital, issued with the condition that there is an oxygen device. ситуthe radio sometimes falls as much as 65% (yes itself in shock), we use at-5.5-6, it's up to 7. But it should be understood that for each individual setting, if for 1L then the oxygen output is about 93%, We use 5,5 is about 40%-35% oxygen, you and I breathe air about 24% O2 content, when using ситурация-92-95%. Without it 88 and below. With every day to moan better, the main thing is not to let you get used to it, try to do without it, develop lungs, used more than 2 weeks, Time shows 50 hours.

The device is packed in an expensive box with 1 si thick foam plastic very high quality and good faith. The device itself without damage, is workable. Instruction in English, not detailed, had to look from the Internet. Delivered to Altai Territory in 15 days. Seller recommend

It came quickly, to Valdai 2 weeks. Assembled, connected, everything works. Grandma is happy, grit will breathe. You just have to ask the doctor about the duration of sessions
