Good quality
Plumber wanted $800 to install two press fittings. This was a better deal. Great quality, easy install, perfect fit.

Great for extending pipes behind walls in home modifications
I just refuse to use Sharkbites behind walls and rely on a tiny oring to hold back water over decades behind an interior wall. I'm also not a plumber so I don't / can't sweat fitting to copper pipes. The compression fitting makes a great connection to the existing copper pipe and the PEX transition, when used properly with PEX crimp rings, should provide a reliable, leak-free connection.

Quick
Just received these. But they look like they're going to work. Much easier and faster than solder.
