SMACO Mini Scuba Tank Diving Gear for Diver 0.5L Scuba Diving Tank Oxygen Cylinder with 5-10 Minutes Backup Diving Equipment Kit for Underwater Exploration Emergency Rescue Small Pony Bottle S300

Got this for a trip with my son. We like to dive and plan on using this regularly. I'm impressed with the design and the weight (super light) but the pump amazes me. The tank pumps up fairly easily, but takes a bit of time to do it. It's not just a few pumps of air and ready to use. We have two tanks and to get them to about 2000 psi (to give enough time in the water) it took about 10 minutes and multiple trade offs pumping each bottle. Not sure how that's going to work on the beach but we're giving it a shot.

At first i loved it but now it's only been 30 days and it won't hold the air for more than a few hours. So i have to fill it right before i want to use it. The to contact seller but it won't let me. Not happy don't buy

works well , does exactly what it needs to.. it takes a very long time to charge it up. about 15 minutes of pumping to fill up completely.

Seems like a really good tank and can’t wait to use it!

Impossible to inflate, and the pump is leaking. I managed to get it up to 100 and went for a short swim, managed to get about 10 breaths

Didn't work

There's a reason people are trained to dive....it can be very dangerous unless you understand the physics and psychology. Don't take my word for it, just google crowdfunded diving kit danger - and see what you come up with. Read the articles, see if you can find the comments section on similar products.

The pump would not work so I had to send it back and get a new one.
