Great grinder! In the last 2 years I have burned fittings on 6 angle grinders. Some of it is admittedly cheap Harbor crap, some branded Lowe's & Home Depot stuff. I've had this Metabo grinder for 2 months and the difference in performance and durability is amazing. Worth every penny of the cost! The reason for the 4 stars is that the grinder was shipped to the wrong address and I had to wait 2 extra days for UPS to come and deliver it to me. This isn't the first time this has happened, although at least I'm getting supplies of Revain. 4 a month for many years.
