I bought one in blue and my Fiancé got one in black. We got them back around Christmas and now that its summer we are trying to use them. Very confusing, doesn't come with instructions. Im pretty sure the black one is broken when you try and fill with air you hear the mouth piece hissing and the button doesn't release air. Plugged up the blue one to the compressor and its actually filling up but the mouth piece is also hissing and its taking a very long time to fill the valve goes up extreamly slow. Hopefully im doing it right since the are No instructions.

Works good, but runs outta air quickly. You'll need a special electric air pump to fill it up.

Not worth the money. Hard to fill and 0 instructions on how to do anything. Plus the gauge is on the wrong side of the bottle so you have no chance to peak on how much air you have left without getting this out of your mouth and loosing so much air. I’ve seen better versions of this for sure. Spend an extra 50 bucks and getter a better quality with a pump and a separate gauge if you actually want use out of it.

Good buy

It is perfect I like it very much
