Amazing deal. Got it at a snap up action, it was delivered in 18 days through EU Priority Line. Yes, it is the 110V version, got a voltage converter for it to be able to use it at 220V. But for this price... People should read the description before buying. Oxygen concentration decreases as flow increases, this is normal and it is what this device is capable of. You can't expect 9 lpm with 93 percent saturation, no device of this type and size is capable of such specs. All in all, a good purchase and is good to have it around. Thank you Banggood!

send wrong spec, instead of 220VAC, they send 110VAC type, and till now no response. very disappointment, look like cheating
