Bought this mic as a cheap backup for my SM58s and initially I was pretty impressed, considering the price. Sound quality was surprisingly clean and crisp, a little harsh and less refined than something like an SM58, but at the price it really isn't that far away from the much more expensive branded dynamic mics.
So initially was very pleased with the mic, so much so that I started using it as a secondary mic for gigs. After a few months use though, the XLR input broke, and when I took a look inside the connections were flimsy and not built to take any abuse - which you may need for a stage mic!
So overall - a good cheap backup mic, impressive sound for the price - but not very robust. If you treat it carefully, should be fine.
