Not a bad product. It works pretty well and does the job. The price is very reasonable for the product. I bought 2 of the 1/2 inches, 1 of the 3/4 inch and 1 of the 1 inch models. The issues I had were that I had to adjust it on my 3/4 inch collar leather with pliers because the collar I had was too thick but I made it work, and I had to curve the 1/2 ones so they fitted on my cats. It worked out for the 2 nylon cat collars and the 1 inch and 3/4 inch leather dog collar. So I recommend it overall
