Well, somehow I broke the sleeve ring of my OS Systems dry glove system. I called the company to see if I could get just one ring (of the four) and the person I talked to said she only heard of selling the complete system. After asking if it wouldn't be good PR just to put a ring in an envelope and send it off to a customer, she said she'd look in to it and the next day they did so. Hopefully, it will arrive in a couple days. Hurray for OS Systems!!!
