0.5L Mini Scuba Tank with Pump, Portable Diving Tank, Lung Tank Kits with 3000 PSI Max Pressure, Reusable Scuba Diving Kit Gear with Pump Underwater Breathing Training

I thought these would be fun to use in the pool and at the lake. I havent tried the lake yet, but they worked great in the pool. It is pretty straight forward how to use them. They feel very comfortable and no water leaks in.Some reviewers complained about the hand pump not being able to fill the tanks to max pressure, but a hand pump is not for that. The hand pump allows you to use the tanks without needing an electric pump, but a hand pump will not replace an electric one.I would highly recommend these tanks.

I have no words to express how awesome this product is. I went to try it at once, and its SO SIMPLE. I stopped scuba diving since I was annoyed of all the hassle with the gear, but this made it so easy, effortless. What an experience. I was diving next to the scuba divers with no gear.... Just to see their faces was a poem. I still have to figure out a practical way to recharge, but still, it's worth the effort. I highly recommend trying this thing out!

Unless you want to invest in the electric pump, save your money. There is no possible way to get air into these tanks in any meaningful amount unless you are a body builder and even that would take an hour to pump up. Complete waste of $$.

I like scuba diving and wanted something to just throw on quick. It’s shallow in front of my house and this setup works perfectly. It’s nice to snorkel and then when I want to dive down I can stay down because I have a few breaths. The pump also works great. It takes a lot of pumps but it’s better then using my main tanks to fill the little tanks.

I was seriously impressed with this mini scuba tank kit. It's lightweight, easy to use, and perfect for short dives or underwater training. The pump works well and everything fits neatly in a carrying case. I used it for a test run in a pool and later in shallow open water. It delivered reliable breathing and a surprising amount of air time for its size. Set up was simple and the build quality feels solid. Definitely a great buy.

I love the portability. My only issue is that there's no way to know how much air is left in the tank because the gauge is not visible while in use.

We got these to try at the pool and lakes we go to. So far it’s been a blast! Me and my fiancé have only tried them in the pool so far. It’s been extremely fun to test them out. We cannot wait till summer to use these at the ocean and lake. Love that they are refillable and came with everything we need to get started. It took some getting used to since we have never used something like this before. But once we got the hang of it, it’s a blast! Highly recommend for anyone who’s looking to get into scuba diving or just for fun exploring around while you’re swimming.

It working good under water although it’s impossible to fill it with the pump too hard. I used the adapter and scuba tank.The kit was ok although one of the tanks was damaged, air leaking , I contact Amazon and they solve the issue for me
