... is one better than the other and if so why?  Thanks

I've only used the clickety clik. You would only have to buy one probably.I've never seen one break.If you think you need a clicker,you probably do.    

I've only shot the clickety click also. Never had a problem,except for wearing out the spring steel after a few zillion shots.

I have never used one but have neglected my shooting practice for the last couple of  months  and figure it would be a good time to try one out.    Thanks for the heads up guys.  

Kricket and Klickety Klick are the same basically--one is just a bit longer on the base than the other is all......Dave

One thing I do on my Clickety Clicks is to cut the base down until it is the same size as the spring steel. Just shortens it up a bit so I don't have quite as much hanging on the limb.

Ron, I have used both and prefer the Crick-it over the Clickety-Klick. Both work the same but I like the Crick-it because of it's smaller size. In fact I have a new Clickety-Klick still in its wrapper with instructions you can have if your interested and not in a hurry. Just send me a PM.
