The Good: Its stolen, great parts for cheap. Looks great. Can flip it without it looking to weird.
The Bad: Nothing bad
Ive never had any problems with slipping. I believe thats user error and improper installation. just like with any stem, you have to make sure that the bolt plate is on evenly and tightened well. Personally the worst stem is the odyssey elementry, piece of crap. It makes it difficult for quick adjustments.
