If so, how have they held up? Have you had any issues with them?

I am not mechanical, but as far as I have seen they work just like the aluminum ones (The robot currently has 4 plastic and 2 aluminium) with no issues. My only recommendation is to make sure to put 2 bearings in each block. I wasn't given enough bearings when reassembling, so our wheels are angled with only 1 bearing in each block.
