On the plus side it is sturdy and has rear dust exhaust ports, which is great if you do a lot of grinding. On the other hand, it vibrated wildly when first started up, even bolted to a steel pedestal. After checking the mounting bolts, the shaft, and anything else that moved or could be tightened or adjusted, I found that the Dewalt wheels were the problem because after installing another set of wheels most of the vibration disappeared. It still vibrates more than my 8" Delta grinder, but it's about the same as my old King Industrial that burnt out. Overall certainly not the greatest, but a decent price and rear exhaust, so I'm keeping it.
