My daughter loves it. She only uses it in the pool but enjoys the extra time under water.

These we thought would be good to use instead of our real gear to look for pool leaks. They would not close to hold air. Very disappointing . No help on any site I tried. We wanted them to work.

Game changer for snorkeling! Let’s you go just a bit further to see the best of underwater beauty without heavy scuba gear. Easy to use. Solid construction. Easy to pack! We’ll never snorkel without them again! Great product.

To fill a high pressire tank with this pump you need to be arnold schartzenegger...for all but power lifters that aint gonna happen...yes I am serious I weigh 220 and at 3000 psi my feet came off the floorvand i still couldnt pump it....opt for an electric high pressure pump.

What an absolute piece of garbage. I bought it over the winter finally brought it out to use this summer. Neither regulator works.Good luck trying to get a hold of someone when trying to get an answer on how to FIX the regulator. Because you will need to know how to do that. All you will find is a one page BS adjustment piece in the case. What a huge waste of money. I was forced to get one star is a rating. I didn’t even want to do that. It is that bad.

Doesn't come pre filled. Hand pump takes 35 minutes of straight pumping to get very little. Extremely difficult to pump. Have to figure out another way to fill with air.

The media could not be loaded. Muy buen producto

I thought this was the coolest idea when my brother bought this for me for my birthday. I put it together and tried to pump one of the tanks up for over an hour. The pressure gauge doesn't move at all. It has some air in it thought. I can take maybe 4 breathes and it's out of air.There's no seal leaks, all the rings look good, I depressurized the tank and started over two or three times. I had my brother and dad take a look and they couldn't figure it out.My next step is to take it to a dive shop and see what they say, but it kinda defeats the whole purpose of being able to pump and go. Ideally, you'd want to maybe spend 5 minutes pumping one up to go dive for 30 minutes or so.If the dive shop tells me I'm doing something wrong (I've been diving for 18 years now, just normally have them fill the tanks), than I'll update my review.
