Seems well made, and the materials used are nice. I wish the clamps were just a little bigger and had more grippy ends, but your mileage may vary depending on your needs. We tend to use things a litter rougher, and I feel these are perhaps not meant for such abuse. Regardless, if a nice collar/clamp combo is what you're looking for, ya can't go wrong with these! Gad to have em in our toybox.
