I found nothing to dislike about this product. The thickness of the grinding discs is powerful enough to cut over the whole factory floor.I worked with them continually for over an hour and the discs showed nearly no wear at all. The price is also reasonable.

My old machines works well with these tools,but I will buy a new machine, HTC or Scanmaskin grinder.

Work long time and still left a lot diamonds after my job last week.

After checking some prices of similar grinding disk at local stores, I purchased them, The tooling chewed all kinds of concretes I could give it.

This grinding disc worked great on my flooring I had to be careful and use water because it was a little too aggressive but still a great tool.

Order received.Polished concrete track. My husband happy. Thanks to the seller.

Works like it's supposed to. Decent quality, delivered quickly.

Looks very qualitative. The diamond tools are very thick. I'm satisfied.

It words great for grinding down the high spots of concrete surface.

Would test it next Tue.

The disc is a beast! Removes material in a hurry.

Works great. I'm grinding the lousy surface off a 60 year old garage floor so as to get a good bond with
polymer surfacing cement.

Did as expected. Did a large patio ground down plenty of life still in disk

My dad and I used this to grind mastic up in the kitchen. It worked great.

This disc is amazing how much concrete it will grind off.

I Used this to taper garage concrete front lip down to be level with driveway concrete, and to do same to several sidewalk segment ends that were no longer level. Did great job, and pretty quick.

I had to remove high spots off my garage floor where it settled and came to a peak in the middle which made it impossible to get a good seal between the garage door and the floor.This tool worked really well with my angle grinder and enabled me to fix a long standing problem in an afternoon.

Creates a smoother finish than I expected.

I couldn't believe how good this worked for the price. Put it on a 4 angle grinder, kept the concrete wet and it worked perfectly.

Fast shipping, and nice packing. Seems good quality.
