These are a fair swivel for the price but size is smaller than expected. This is the 2nd set I have bought and they have been built well. I have been using them for a while fishing for large Kamloop rainbow trout, up to 15 pds. These trout hit hard and do some pretty wild runs and I haven't had a problem with them.
The Cabelas brand ball bearing snap swivels are the only kind I use. They are easier to snap the the other brands I tried and they keep my lure straight when trolling. Easy and quick change over from lure to lure.
Cabela's was out of the swivels I normally use so I picked some of these up expecting them to be even better since they had a higher price tag, and I was wrong. The split rings are incredibly weak, and even the fact that these attach to the line via the split ring is disheartening because it creates a surface that isn't perfectly flat and bites into the knot. I have had several of the snaps open up while tossing out 3/4oz swimbaits and having the swimbait go flying. When fishing tournaments it is nice to have certain rods paired up with a quality snaps to change baits as the bite changes and these aren't doing it for me. I will stick with my "cheap" snaps.
