2L Mini Diving Tank, Is It Worth It?

I tested the SMACO 2 liter mini scuba diving tank. How long does the mini diving tank last, how much does it cost, is it dangerous and much more info. I have worked more than 7 years as a commercial diver and have one 1000 dives, so I know what I’m talking about and I do have fair amount of knowledge about diving. I am not paid to say anything positive or negative about this tank, am I also not getting any commission from sales. This is a honest review and I am not paid to say anything positive or negative about this tank.
