The only problem is the Montecs have a problem with the tips breaking and they will not replace them. Search for reviews on the montec and you will find them.
Magnus stands by their product and will replace anything with a lifetime warranty. I am not sure about wacems warranty.
I've never once had that problem, nor heard of anyone that has. I'm not saying that it doesn't happen, but it sure sounds to me like it's something that is extremely rare. My Montecs have worked flawlessly for me. I'd recommend them to anybody for any animal. It'll put 'em down.
