We got this to use for an upcoming Los Cabos trip... Upon inspection of receiving the product you can tell the quality is there.... It took me 2 minutes to setup. All worked flawlessly... The seal on the regulator seemed solid. It does come with extra O rings if needed. You can strap harness it to your back or across your chest. I would guess on average about 8 minutes of breathing time..It is very much like spare air if familiar with diving products. You can refill the bottle and use it over and over.... It is fantastic if needing to retrieve items on the bottom, clean a hull or just do some leisure shore free diving...I like the simple lightweight design - It will definitely come in handy and enhance our underwater activities...Cons- It will take a plethora of pumps to refill bottle - Will definitely use a scuba shop instead to refill4.7 of 5 stars

Solo necesitó un pequeño ajuste y funciona bien...

I bought this for my grandson who is ten years old. The air supply hasn't lasted anywhere near ten minutes. More like four to six minutes. Also the relief valve on top of the unit leaks. The screw on top gently compresses the relief valve and it will leak air. I lightly unscrewed the top so it won't contact the valve in order to keep air in the tank. Otherwise the grandson loves it and it works fine under the above conditions.

Just as described in the description section. No complaints. Great quality.
