I have never had any problem with them. They drop right in and are very easy to adjust. If you are going to go down into the crazy low range like Benchrest (2-5 ounces) I would recommend having a serious gunsmith install a customized trigger, or perhaps one with a two stage setting like the old style rifles, just because that weight is CRAZY low for carrying the rifle for any reason.
As for normal adjustments under 2 pounds, the Rifle Basix is a solid trigger and it is pretty heavy duty for field carry and isn't as pristine as some others out there that require a bit more care and comfort (Jewell).
I like them and haven't had a bad experience with them yet.
