Mini Scuba Diving Tank with Sub-Mask, 0.5L Dive Portable Lungs Kit，Underwater Breathing System for Family, Party and Trip Perfect Professional Diving Packages

Directions suck, tank does not fill up at all, the directions are of a product that I was not sent. Pump is different Likely a gimmick, would love a working product that was in the directions

Hay que tenerlo! Espectacular! Lo unico en contra es lo que ya te explican: duricimo inflarlo a mano! Hay que tener el inflador electrico si o si. El resto…. Puro placer.

great cuality .

When I first received the unit, even hundreds of full strokes on the pump wouldn't show any increase in pressure. When I checked the fittings on the tank and pump, I found all of them loose. Also, you need to "oil" the pump shaft (look carefully at the pump instructions). After tightening all the fittings and oiling the pump shaft, it took the expected 500 pumps to bring the tank up to full pressure. I have a large lung capacity, so the tank only lasted about 5 minutes and the last 100 strokes of the pump were far more difficult than the first 400...so I bought an electric pump that makes life easier. The mask seals well and the double-snorkle feature is nice when not using the tank.

Product works as expected but after the first handheld pumping of the tank you will want to upgrade to a compressor and external filter for cleaner air. Absolutely had a blast using and directions were spot on “manual pumping is a ton of effort “. Great work out 🤪.

Missing pieces. Spent a lot of money on it to get it and not all be there. Highly disappointed

Overall, I've been very pleased with this set. The tank is only good for a handful of minutes - between 6-8 minutes is what you should count on. It works well in tandem with the snorkel mask and standalone with the regulator. I haven't had any issues with the mask fogging. It isn't overly large so it is easy to use without being heavy or inconvenient. This is great for short dives, in my case, for shells and/or fossils. It could also easily be used as an emergency/back up tank. The pump it comes with it is not efficient. Even being a small tank, it is just not effective or realistic to try and fill a tank in this way. I can fill this little tank within thirty minutes with my compressor. Overall, I'm happy with this set.

Purchased as a gift but it takes way to long to pump, and even spending 30+ minutes pumping the tank still wasn’t full.
