Review on Adjustable Dog Training Collar with Comfort Rubber Tips and Quick Release Snap – BABYLTRL Prong Collar for Dogs (Small, Medium, Large) by Todd Look

Very pleasantly surprised by the quality of this collar! Delivery was very fast and came with 2 extra links and extra rubber tips. The links are very thick and heavy, comparable to Herm Sprenger 3.25mm links. You can take them apart by hand if you have good hand strength, but it's difficult and that's a good thing! Seems very safe. The ends of the tines that touch the neck are beveled and smooth very well, you don't even need the rubber tips provided unless your dog has a metal allergy, but they glide on very easily and hold securely. Given the durability of the links, double loop closure and locking plastic quick release buckle, I find it safe enough for even very large breeds (I've used it on a 140lb St. Bernard), although I always recommend using a backup, like a carabiner for added security. The only caveat is that the collar doesn't have the martingale action that gives the standard collar correction an edge, but instead works under pressure. This makes it the best tool for sensitive dogs or for maintaining manners in dogs that have already been trained to wear a spiked collar. Stubborn dogs may need a collar with a sharper correction. Overall a very strong collar, very easy to put on and take off and a good option for most dogs!
