Smaco scuba tank review

Below are some reviews from real users who used the mini tank and submitted their reviews on amazon.


  • “My dad loves sailing so I got him this for one of his trips. Not only did he use it to scuba dive in the middle of the ocean, but he also used it to fix the engine while in the middle of nowhere. This can make trips better or be a lifesaver!”
  • “Bought this for my son to use in the pool. He gets about 8 – 9 minutes of air per full tank. That’s only if he didn’t take any break. He loves it so much that we bought a second tank to extend the time. We bought a high-pressure compressor from Amazon so we could fill on our own as it would get expensive in a hurry if you had to pay someone else for each refill. Each refill takes about 30 – 40 minutes. Well worth it!”


  • “Good quality everything put on with precision it includes a briefcase to carry everything very well, but its price is high, because these useful bottles are not much since at most you endure 10-15 min and recharge it again, and never empty them completely that can rust and break a lot of eyes they require care.”
  • “It started with 15-20 mins of air…I have tried 3 full tanks now and each time I only get 6 mins!!!”
  • “A main complaint from users regarding the mini tank is that it doesn’t last up to 15 minutes as mentioned by the company. Anyway, the lasting time would vary depending on the frequency of breathing underwater and the depth of usage.”
