Works well but I wish it came with a mask!

Works for quick oxygen boost

I started using canned oxygen when I quit smoking. Instead of inhaling smoke I inhale a couple breaths of canned oxygen. Not sure if I notice any physical changes instantly but it helps control the need for a cigarette. I now take an oxygen breakk with blast than a cigarette break with marlboro. I've purchased other brands for more and less cost, but prefer the price of this brand. I don't mind not having a cup and trigger because they are always too big and awkward to use. The reason for 4 instead of 5 stars is it doesn't seem to last as long and I get less breaths per can. Otherwise the quality is the same or better. I've traded a bad addiction for a good one, or at least a better alternative. Waiting for my second order to arrive and will buy again.

It’s unusable without a separately purchased mask. I bought three large canisters which I CANNOT USE since I saw nothing in print advising that a special attachment is required. I will be going back to BOOST—They’re immediately ready use, unlike this gravely disappointing purchase just taking up closet space. O2 blast, some users are emergency based and the fact that you all didn’t see fit to equip your device with a top that makes it immediately usable, tells me you’re not serious about ease of use, or interested in customers who need the lift due to health issues. By all means, oxygenate the athletes, but until you mask up the device, it isn’t a serious product.

I bought these because they were the most economical of all oxygen bottles. I had no problem receiving them, yet it seemed a little longer to ship than most. Not too bad but a few weeks is pushing it. They may have come through customs, so, be sure where yours is coming from if you’re in a hurry. I had no problem ordering or the shipment it was a straight forward deal and I appreciate this vender getting the product out right away. I have ordered oxygen bottles like these in the past from a different brand. The difference is there is no face cup. This is a spray only. I couldn’t find a cup to buy separately but I half heartedly looked. It is not hard to spray into the mouth or nose. However, the amount wasted is not known. Oxygen is oxygen, right? IDK. I used this and it felt like I got a burn or blisters or a sore spot on my tongue where the air passed thru my mouth and my sinus became a little raw. I didn’t get this from my last bottles of a different brand. Also, there is a noticeable difference in quality. For instance, I didn’t get a noticeable relief when I was out of breath after exertion. The other brand was very effective. Also I didn’t get the boost to help make me feel alert when I was drowsy during driving. Again, not so with the other. Since the affects were minor to Nil and the burn I cannot recommend this if you really need it to work. Plus the burn concerns me of chemicals I’m unaware. This is too bad because it’s more affordable and receiving it was easy enough.
