I was a bit hesitant due to some negative reviews but I was impressed. It costs money. I got the Heavy Duty and was glad it was actually "Heavy Mode". Is stable in the hand and has a certain weight. There are different sizes to choose from when using. I was able to use this with 2.4-5 ounce pieces of leather SAVED with no problem! These are 8-10 ounces of leather that he pierces easily and without fail. I would say that for this price it is very cool.
