High quality, added gauge, fits pwc container
Came with a pressure gauge which I consider an upgrade from what was pictured. Still fits the storage container perfectly. 1997 Yamaha WaveBlaster 2 1998 Yamaha WaveRunner 760XL

Seem solid and would buy again.
Stout fire extinguisher. Maintaining pressure after hundreds of rough miles on my RZR. Liked it so much I bought two. Easy enough to figure out. Great value for the money. They're not heavy either which is nice. Thankfully I haven't had to use them and hope never to.

Good purchase
Thankfully I haven’t had to use this, so can’t speak to the quality of the product, but I like the size and it passed the game warden test.
