I bought this for use in my EDCO edger to remove 2 coats of epoxy paint from a concrete floor. I have used it to grind 1500 square feet and it has finally worn out. Leaves a smooth finish and has outlasted my expectations. Well worth the price.
Pros
The product arrived much earlier than expected and works great. Would order again from this seller.
Cons
The 7/8"-5/8" arbor may not fit all angle grinders
