Is nothing like the picture. The bag is thin, the brand is not listed and the mask fits for a child.

I was looking for a face mask to use with my O2 concentrater because when my nose got congested, the cannula could not deliver the O2. I had no idea what a "Non Rebreather" face mask meant. I got it and used it. It seemed to work. When I spoke with my medical supply company about the mask and asked if they carried one a bit shorter, I was advised the mask cannot be used with the concentrater because the user's exhaled air goes into the mask and combines its CO2 with the O2, after a short while the CO2 is dominant and can suffocate/poison the user. Only cannulas can be used with the O2 concentraters. I stopped using the mask. I did not investigate the matter further. The item says it is an oxygen mask, but cannot be used with a concentrater, according to the medical supply people, so how can it be used? If interested in this product, call your supply place, doctor or someone who knows about these things for advice.

It was shipped in a bubble mailer and was received fine. There are two major issues with this mask.
- The mask simply doesn't fit - it leaks a all-around. That is okay to some extent for other masks but for this non-breather - meaning, you don't re-breath the exhaled air and you dont inhale air from outside. The way it should work is, when you inhale, the inlet valve opens and when you exhale, the inlet closes and the valves outside the mask open and let the air out. It failed in both the cases. The inlet valve stayed open when exhaled and at least one (sometimes both) the valve that was outside stayed open. Besides, the fitting wasn't good and leaked all around. The metal tab above the nose bridge can be pinched but doesn't help at all. If you are trying to get pure oxygen, you will be disappointed - you will be inhaling the outside air that enters around the mask and when you exhale, the bag fills up with your exhaled breath.

I bought two of them, both had the same issue. I verified the flow rate, other fittings - but it turned out a really a bad design - the flimsy valve and poor fit has serious design flaw. I think they are trying to offload the stuff that has a major design flaw.

This Doesn't work. I wish I could give zero stars.

The product listing very explicitly states that the item is a non-rebreather mask. It looks like the product photo has changed since I ordered the product and since the description may get updated as well, here's the original description straight from the product page, "Elongated oxygen mask molded of soft, transparent material. Tubing adaptor swivels for use on either side of patient. Soft vinyl reservoir bag. Complete with 7ft of oxygen supply tubing." What I received, pictured with this review, is what's commonly referred to as a "simple" Oxygen mask. It has no reservoir bag and no valves, making it useless for the intended use of non-rebreather masks - delivery of a high concentration of Oxygen. Reading the reviews, it appears I am not the only casualty of the bait and switch. The product photo when I ordered the mask was a stock photo of a non-rebreather mask. Now the product photo is a simple Oxygen mask. However, the product details still describe a non-rebreather mask. Given the mixed reviews and current ambiguities I suggest readers select a different vendor. I returned mine for a refund.

It's decent but that bag to catch the excess O2 is the same material as generic sandwich bags. It's not going to last long at all!

Works pretty good, as designed. Only shortcoming I notice is that you have to apply a little pressure to it to get a proper perfect seal. It may be that tightening the string loop would correct that. Everything else is good.

I found that the one-way valves leak in the reverse direction, making it NOT a true non-rebreather and allowing room air in to reduce oxygen purity level. It is just OK for higher flow than a nasal cannula allows.

For the money, great, slight easy mods to make good. As expected.
