One of mine arrived DOA but they replaced it no with no problems, overall very good part, they do get a bit hot so you might want to figure out a way to cool them

Awesome!

I tried fiddling with a UL2003 chip for a while, but the project stalled because of the complexities of reversing the current though the stepper motor. This does it for you! Superb!

Driver and heatsink works great

I bought this for my REPRAP after burning my previous one. I was surprised to find that this driver was per-assembled as the previous vender I had to solder the parts.
