Works great
As a Master Plumber, I don't use push connect fittings so when I transition from copper to pex I would either use a solder transition fitting or a pro press one. Since discovering these, they are all I use.

All a miss but one so far
They're not made right used 5 so far and only one holds and doesn't leak. Cut off two other fittings installed new ones and they leaked too what a waste of time

Works Well
Works well for 1/2 copper pipe. USPS was a day late as usual. Only recommendation would be if the company sold these for 3/4 pipe as I had to use a shark bite since LOWES nor any other hardware store sells them.
