I bought the diving set gear with a 1 l tank and a hand pump. I had to return it after the first use because it was impossible for me to just fill one liter of compressed air onto that bottle by hand. You absolutely NEED an electric device for that. I was only able to fill it like almost halfway through... I managed to get a refund for the gear, but in the end I ended up losing €100 for the transportation fees. They should know better than to sell crap gear. Now I understand why there is not one full video of a person filling a 1 lt tank by hand. Don't be fooled like I was!!

I bought the S400Pro mini diving cylinder from SMACO’s website and overall I’m very satisfied. The ordering process was simple, the product description clear, and checkout smooth. Shipping was faster than expected—my package arrived in less than a week, well packed and with clear instructions.

Before ordering, I had some questions about refilling and safety. SMACO’s customer service replied quickly and explained everything in detail, which gave me confidence.

Using the S400Pro has been a good experience so far. It feels sturdy yet lightweight, easy to carry, and simple to fill at a local dive shop. I’ve already used it on a few shallow dives and the airflow was steady and reliable. The first setup took me a moment to figure out, but after that, it was straightforward.

Overall, I’m very happy with the purchase and I strongly recommend the S400Pro.
