Solid build but not for all valves
I bought this Mastercool tool for my HVAC work, and while it’s built really well, it doesn't fit some of the larger bore valves as claimed. It works great with standard R12 and R134a, but I was a bit disappointed it didn't fit everything I expected. Still, it’s handy for the common sizes!

Good tool but hard to get used to
The valve core remover does its job well, especially with different valve types. However, I struggled a bit to figure out how to use it effectively at first. Once I got the hang of it, it worked fine, but some clearer instructions would have helped a lot!
