## Customer Reviews

### ⭐⭐⭐⭐⭐ Happy with my unit
*by S***W on January 18, 2025*

Just be aware that I've updated my review, because I was originally upset that my order didn't fully arrive with the only shipment status I was sent. When I got the order it was just the tanks and vest, but was missing the air compressor for my full base kit.It took an additional delivery that I was not clearly informed of to realize the additional unit for my purchase.I am glad that my full unit arrived and did a test fill. Was able to fill it to the maximum capacity and seem fully functional. Look forward to putting it to use.
