The unit performed as expected. It stopped working during the pandemic. GVS does not having a service centre in my city (Mumbai). They requested I send the faulty unit to them in Hyderabad. By the time I got the unit to them, the warranty had expired and it turned out the unit was damaged by water during use (not covered by warranty).The folks at GVS were however very patient and considerate and agreed to fix it without cost.I got the product at a good price. The product worked competently. The service has been top-notch.Recommended.

Product delivery well on time, had to buy 1 kva stabiliser ( V-Guard VG100 ) as mandated by the label on unit. Easy to assemble, optional YouTube video available for reference. Additional filter, canuli provided. For warranty, you need to email/ WhatsApp order details. Shall provide detailed review post usage.

Oxygen concentrator is really good, easy to use, value for money and having less noise.Moreover it's customer support is excellent. Customer care executives are very much supportive and resolve your queries quickly. In case of any issue, company provide free pick up and delivery of machine during warranty period.

Over sound

Good product but does not show oxygen concentration. We don't know if it's 93 per cent at 5 litre concentration.

This equipment is very silent and peaceful, working nicely last three months.

My father is using this concetrattor for more than four years now. It worked absolutely fine. Only recently we faced problem to much heating. It was because of fan was not working.Product was out of warranty but the staff is so nice they sent new fan on my home address without any cost. And guided how to replace the fan. The machine is working perfectly fine.
