I have not had much time to play around with it yet, but it is built like a tank and seems to be a very solid machine that is pretty easy to use. I have no experience with coil binding, yet my first attempt went really well. I didn't realize I needed to order the coil crimper separately, so with my trial run I used a pair of needle nose pliers and managed okay - promptly ordered the crimpers though and a couple larger sized coils. I believe this will provide much more functional binding for us in comparison to the comb binding that we were using.
