I received the machines. Everything is good as usual, good machines, fast delivery, good service, all are great. Thank you so much. I think we can establish long-term cooperative relationship, if I have more need.

Current using machine is good. It will be used 1,000 hours soon. Previously used machine was broken almost 1,000 hours used, but your machine condition is still good. This machine's performance is great! Displacement is higher than another supplier's machine. What's more, they are light and easy to carry. We are highly appreciate these points. We are thinking about the next purchase now.

The 5L oxygen concentrator that i bought was pretty good, it reaches what is told in term of oxygen purity and the equipment is robust but not to heavy.

Excellent product quality! Very happy with purchase. Hinor is an excellent oxygen concentrator supplier that made it very easy to purchase and handled my shipping problem very quickly. Thank you and happy to do business again in the future. Highly recommended!!
