Review: better than the more expensive brand i used to have - been using these for a while now, a bought 3 kits for my technicians and they work fine, just like the more expensive ones i used to work with and it comes with a lot of useful adapters, on one of them i had to tighten a part to stop a leak, it's good to know i think to mount the gauge just slightly hand tight otherwise you will smash the O-ring
Review: Fittings do not seal correctly. - Ordered one and the fittings didn't seal correctly and it leaked. Ordered another one and it was the exact same way.
