Query: Just get the book

The book looks ok, although I haven't really gotten a chance to use the techniques. However, the clicker that came with my kit doesn't make any sound whatsoever. Apparently other people didn't get broken ones, but I did. It's not worth shipping back, so I'm just going to buy a new clicker that actually works.Meanwhile, my cats hate the shriveled up little treats that came in the kit. They sniff them, lick them, and then ultimately leave them partially re-hydrated on my floor. So I'm going to have to figure out something else to use for treats. Really wish I'd just gotten the book and skipped the kit.
