I've had my leatherman MUT for abut 3 months now and it has more than paid for istelf. It is very well put together and has just abut everything i could need from a multi-tool for my primary use (ar-15's). The only issue i had with the tool, which is in no way a reason to not purchase it, is that when using it as a screw driver it doesnt quite open all the way straight or close fully. This is a small issue if at all. Just makes it a little harder to keep the bit steady on the screw when you are in a hurry. Other than that it has more than exeeded my expectaions. Bottom line; if you feel the need to have one, buy it, you wont regret it.
Pros: very solid quality and ease of use
Cons: minor design flaw
