Very sturdy collar. The clasp is easy to unfasten, but the dogs never manage to unfasten the collars themselves. The adjustability is good, and I love how large the ring is to clip a leash or a tie-out to the collar. I use these collars on 9 dogs, many weighing well over 100 pounds. I wouldn't use anything else.

My dog is strong. I needed a strong collar that wouldn't snap - not for tie out, but for walking on a leash. My first Retriever collar lasted for almost a year. But I've recently gone through three collars in the past four months. My dog spies a deer, and his hearing completely vanishes, and one good tug, these collars break at the cheap, plastic latch. It shatters like glass. It is no more a "tie-out" collar than a piece of twine. I bought my last Retriever tie-out collar last week and it broke last night. It took three destroyed collars to convince me that they are charging more for a cheaper collar, but I'm a believer now. No more Retriever collars for me or my dog.
