  1. Miles king (verified owner)

    Worked great for me! The tank is light and easy to swim with. I purchased a scuba tank to refill with and it is way easier than a pump. Highly recommend it. My daughter and I use them regularly and enjoy them very much. It seems well built and have had no issues thus far. Will update if anything changes. I have purchased two of these and they have worked well. I would buy this again. Enjoy.

  2. Misc (verified owner)

    I was really excited about getting this to clean the bottom of my boat. It’s tough having to constantly come up for air and it takes twice as long to do so, this this tank is perfect to get it all done in about 10 minutes. The tank is heavy duty, but lightweight enough to be portable, easy to fill, and does exactly what it says it will. Highly recommend for quick underwater jobs.

  3. Chris jackson (verified owner)

    Good quality, I am very impressed with the quality of the tank and the regulator. I did have to take it to my local dive shop to have it filled so I would suggest that you buy the filling station if you plan on filling it yourself.

  4. Max K (verified owner)

    This tank is very small and light weight. I have another tank (a pony bottle) that I use for deep dives. But it is rather heavy and requires a mounting bracket to keep it in place during a dive. This is easier to strap on. It also takes up less room.

    When you compare this to other products that are marketed to scuba divers, this is a very good value. I wont name names, but an almost identical product is being sold for 3x this price.

  5. Hinkydoo (verified owner)

    Good tank. These were originally designed as an emergency backup to the main tank when scuba diving and now they’re available tot he public. You have to do your research first and can’t dive down more than a meter or so without risk but they’re fun for looking underwater for a longer time. I like that it’s refillable with a pump or air compressor.

    Awesome!Super cool! Didn’t know this existed. Live about an hour outside of Lake Tahoe so I’m gonna take it out there and have some fun! Would recommend buying if you want to get a little more complicated then snorkeling.

    Buon prodotto.Ho comprato da poco Smaco mini scuba tank 300, per ora do 5 stelle anche se l’ho usato una sola volta, tutto senza problemi, per chi non é impedito nel comprendere come assemblarlo è molto semplice ed intuitivo.
    Per quella volta che l’ho usato mi sono trovato molto bene, è magnifico!!
