Does everything is supposed to purge is very abrupt
Purge needs to be done carefully we will receive too much air at once

Half litres scuba tank!
Works pretty good. Only downfall is pumping the tank up for nearly 20 minutes to half an hour. For about seven minutes of air.. Still like the Product!

Great backup tank or for a quick/casual dive
I've had my open water license for decades, but it really is a pain to get out all your gear and haul it with you if you don't really plan on doing a proper dive and want to just have it with you in case you want to go underwater for a few minutes looking at something cool. This little tank is perfect to just throw in your backpack and take with you. It doesn't come pre-filled so you'll need to get it filled up if you don't have a high-pressure pump. I use a PCP pump with an air filter and it takes about 15min to fill it up to 2900psi. A normal air compressor obviously won't get up that high, and a simple PCP pump will have small amounts of oil in the compressed air, so a filter is really needed to clean the air so you don't wind up breathing all that junk into your lungs.
