The few locks I've been able to get a shim into were still too tight to allow the shim to go all the way down, so the shim always crumpled.
On top of that, I've never seen anyone successfully use a shim on any lock, only heard of it being done.
Personally, I think places that sell shims are just robbing people since they simply don't fit any lock I've ever seen. Better stick to picking and bumping.

Most mid-grade locks are double latching, which makes shimming difficult, if not impossible. What's worse is that the double latchers almost invariably damage the shims. When there are two latches involved, shimming is a much slower, more difficult process. Thus, I tend to keep it down to just the combo locks, which are slow to open any other way, and to cheap single-latch padlocks. It often helps to work the shackle around when trying to get the shim in; once it's in and buried in the lock it tends to work.
When shimming does work, however, it's lightning fast. I can open a combo lock I've never seen in a tenth of the time it takes someone who knows the proper combination to open it.
Some of the places selling shims are rip offs. A lot of the shims are just too flimsy to work, and, in rather ironic rather, some others work just fine but are made out of a very low grade steel such that they tend to oxidize over time, even when still sealed in the poly bag, as to make them unusable. Thus, when dealing with shims, buyer beware.
I made a nasty set out of manganese steel sheet that have yet to fail me, and I've blown through several dozen coke cans making crude, one-time-use instruments.
