Query: Great buy!

I once saw someone on YT used this for their belts and I decided to get one too, esp. since I have a small waist and there wouldn't be enough holes on the belt to fit. I am glad I bought it bc it works great. I have only used it one time but no difficulty at all. I gave it a 4 star because it was a bit difficult to switch to different hole size. But other than that, definitely a great buy!
