I have the odd

LM multitool and apart from a bit breaking off from a freestyle cs, that I wrote about a few months back I have not had any problems.
My most used LMs are the Micras.
I find that the older ones (marked USA) tend to have loose scissors and some rust on the tools.
My newer ones are fine.
Also, Squirts tend to have quite tightly packed tools and tend to gum up, so they need a good cleaning every few months.
