These work beautifully, and I would buy them again should I need them.
Two words of advice: 1) Get a few extras, particularly if you've never used a compression tool before. I messed up just one of them, out of about 35 I had to do, so it's not hard to figure out. 2) I did get a blister in my thumb, after "wiggling" in the first 20 or so unto the coax cable. So wear gloves or use some tool to get these on the cable prior to using the compression tool to lock them in place.
Pros: Rugged
I would recommend this to a friend!
