Is this a good 50mW Laser?

Hello! I am new to lasers and am currently looking for a good 50mW laser for under $20 (Just to play with :P) and I came across this one on Newegg: Black 50mW 532nm Green Laser - Newegg.com

Is this laser good? If not, what would your recommend? Will I need to spend more?

Thanks!
