Just takes a little practice. Once you get the rhythm you will start building arm and grip muscles. Wish I knew how it works!  -  Monday, December 01, 2008 ok Reviewed By: Susie (Clinton, MD) My husband had the hardest time getting it started and it ended up dusty on a shelf. I think there's something you can buy that starts it off,... but I don't know if it's worth it?  -  Saturday, December 13, 2008 Just bought one Reviewed By: Ray (Georgia, Vermont) A buddy of mine from the Navy had this a few years ago and I've always wanted to get one. I am starting to develop arthritis and have wrist and arm pain sometimes. This will be a fun way to exercise and build hand and finger strength. It is not hard to start the unit. Just a couple of practice pulls with the string and once you get it going builds up speed quickly. The arm movement required to get it going is a natural movement of your wrist/hand. Highly recommended !!  -  Monday, December 15, 2008 hand exerciser Reviewed By: nolan (west bend, wisconson) this thing is so cool. Once you get the hang of it you better hold on. i did straight for like 12 minutes and my arm felt like numb.
