The test result is good, will contact the factory to buy more, expect get a better price.

I am a concrete contractor, I have bought quite a few sets of the 200 grit for my job.

I bought this tool to grind down some thinset left on a concrete floor after removing some tile. It works great.

Have to be careful on new concrete as this will take material off quickly

Wow what a great Product. these are really just the best grinding heads you can buy.

Have not had a chance to use yet but looks good. Thanks

I love it it did what I needed it so

Great product did the job perfectly

Good products. I used this to get the edges and some profile in my garage in prep for epoxy. I used it dry - I suggest you do the same and get a good dust mask - not a cheap paper cover - a real mask. It did exactly what I needed it to do.

Fast delivery, good package.

Tested it on medium concrete and it worked pretty good.

Same as described

The product is pretty good.

Have done the job very quickly and no obvious wear.I will have a new grinder next month. I will continue to buy segments from your store.

I've used it with grinder at my Bathroom remodeling. It perfectly works on concrete.

Good quality awesome price.

Worked great and has lasted a long time.

Fast Shipping and a great price, item was exactly as expected.

Used this to smooth out some uneven concrete. Work great.

nice product for the price.
