O2 Blast 95-99% Pure Oxygen, 10 Liter Portable Can 10 Pack with Custom Breathing Mask, Increase Stamina & Reduce Recovery Time, Ideal for High Altitude & Sports Recovery

I purchased another brand before this order. It seems the other brand not only lasted longer but the pressure coming out was greater throughout the life of the cannister.

Only contains 1-2 breaths per 10oz can compared to Boost that contains 12-14 breaths per 10oz can.Don’t waste your money.

O2 BLAST in blue. BOOST Oxygen in green. The O2 BLAST mouthpiece is too big. It doesn't fit snuggly and seal against my face. Air leaks out the sides. The BOOST Oxygen mouthpiece fits perfectly. It's smaller. Has a better fit, a better design. No leaks.I put in for a refund due to a defective item and was given an unpaid postage slip. I'm not paying shipping cost for garbage. I sent a notice to the third party vendor via Amazon's refund link. It's 48 hrs later and I haven't heard boo outta them, so this purchase is a lesson learned. I'll eat this one and shop Walmart more I guess.Buyer beware of the product AND this vendor, plus the fact that Amazon left me hanging in the wind.

Not satisfied

Unlike Boost and Biggie, your tops have a tendency to come loose. I also wonder if they develop a very slow leak since they don't seem to last as long as the old style

THIS PRODUCT IS A SHAM! THE SAME PRODUCT IN 2 SEPARATE BRANDS WITH SAME IDENTICAL POSTED VOLUME LASTS 10X LONGER! THE FLOW, EVEN NEW IS INATAQUIT! BUY EVOLIVE BRAND,(comes in larger bottles also) or BOOST. I WOULD NEVER WASTE MY $$$ ON THIS BRAND. WHEN U NEED O2 U NEED O2. YOU'LL B SUCKING FOR O2 LONGER. IF I COULD GIVE - NUMBERS I WOULD. I ? THE VALIDITY OF POSTED VOLUME, EVEN SAY FRAUDULENT!

There is nothing in the cans. 4 of the first 5 cans I've tried (out of the 10-pack) have nothing in the can. Is it possible that all the Oxygen leaked out? Either way, I am extremely disappointed. I am a recovering stroke victim and I thought this would be a good solution to help me recover quickly after workouts as I tire easily.

If I could give this product a ZERO I would!!!!! This product would leak all the air out! And the mouth piece is HUGE! I contacted the seller and he accepted the return and deducted from my refund $32!!!! What a rip off!
