Works brilliantly, durable, worthy investment. Dust or no dust, waste time putting up plastic that dust will escape from and clean up time or spend more time grinding. You will be able to see the work area 100% better with this

Rated 5.0 out of 5.0 by PB Worked as advertised. Excellent product.
Used with turbo diamond cup wheel on angle grinder to remove black mastic from 300 sq ft of concrete slab floor. Reduced dust at least 95%+. Had tried small area prior to purchase using a respirator but dust cloud so immense after a few minutes that I could not see to continue. With dust shroud in place respirator was not necessary. Dust shroud was easy to attach to grinder and still in great shape for next job.

Rated 4.0 out of 5.0 by Ryan Works great but
You will need to buy an adapter for the vaccum. I have a Rigid and it was to big for the hose that they suppled, a little duct tape fixed it. I was grinding old paint off a cinder block wall in my basement and works great with about 90 percent of dust collected.

Rated 1.0 out of 5.0 by Brian Could not use adapter and was not durable
I had to cut off the large end of the adapter and duct tape to my shop-vac.
I attached it to my 4 1/2" grinder, but I guess I was pushing down too hard, and I did not notice the grinder disk was scraping the shroud while using it to grind thinset off a concrete floor, The platic shroud melted, and I could no longer use it or return for refund.
In my opinion, it would have been a better product if the adapter fit most standard shop/vac hoses and the shroud was made of metal.
It did work for the most part for the 15 minutes I used it before the shroud melted, but you need to be careful the grinder disk doesn't touch the shroud in anyway if you want any extended use.

I am satisfied with the product. I have been using it on a concrete stairwell, done in the fifties, that had form seems showing and in some areas a rough surface. Using a double row, five segment, diamond embedded cup it has worked containing the dust. If you allow the contact brushes to lift however you will get some grinding dust kicked out. As long as the surface is in contact with the concrete it will capture the discharge. Some will escape when using with the edge attachment removed, but not too bad. Biggest slow down is the filter on my shop vac needing to be cleaned.

Having ground concrete before with other brand shrounds, I was shocked at how well dustless technology's dust shroud works. The company's claim that that it capture 99% of dust seems a bit understated to me. In addition, the shroud is not rubber, so it does not "suck down" on flat concrete surfaces like other brands. This makes it easer to move across the surface, avoiding gouging. At the same time, the brushes at the bottome of the shroud keep concrete particles from escaping.

I am generally a skeptical person by nature and this shroud was something I wanted to try after seeing there online video and I have to say I was impressed. I saw no dust. My only regret is that I'm using a cordless Porter Cable angle grinder. Need to look for a corded one. I had this shroud connected to a 30 gallon shopvac. I wish I would have purchased the 7" shroud now that I really need a corded angle grinder. I would recommend this to my tile laying friends.

Rated 5.0 out of 5.0 by Videogeek Really Works!
I had a concrete bathroom floor to slope for a standard drain and shower drain and was concerned about the amount of dust it would create. Decided to buy this product along with a heavy shop vac and fine particle filter. I still wore a respirator and would recommend anyone grinding concrete do the same. With this unit I was able to catch 98% of the dust that was generated. I would also recommend checking your shop vac and filter often if you are doing a large job.
