Is A Harbor Freight $10 Angle Grinder Any Good?

I use both the Bosch and the Drill Master angle grinder side by side to see if the Harbor Freight angle grinder is even comparable to a $60 Bosch angle grinder. Truth is that is very usable and works just fine. I wouldn’t fill my shop with these but I would keep one around for lending to neighbors and friends or give to my teenager who is interested in tools or certain projects.
