Rated 2.0 out of 5.0 by proelectricinstaller short life, still messy, serious damages possible
being an electrical contractor, I've drilled many holes in ceiling drywall.
A few flaws with this tool: when new and sharp, cuts well, after 20 holes, the blades become dull and messy.
If you size it for smaller than 8" and you drill completely through the ceiling, the bars hanging outside the cutting portion WILL hit the perimeter drywall and ruin it, needing crack fill repairs.
The dust shield does not contain more than 70% of the dust within it.
Once the blades become dull, you may sharpen them easily on a grinder but even after doing so, it wears out fast.
Using it low speed is not recommended as it is hard to hold steady, at high speed it could fetch up and snap the blades, drywall or completely stop the drill twisting a wrist.

Rated 1.0 out of 5.0 by Hyena70 Not for the average homeowner
I would say that this product is worthless, but that would imply that it has no value. It is below worthless--it will cost you money. I'm very experienced with household carpentry and tool use, but that didn't seem to factor here. I was cutting holes for canned lights and this tool ruined several of the holes to the point the drywall had to be replaced. It would cut several circles inches apart even though the tines were the exact same distance apart. Another time one of the tines came loose in the middle of a drill operation and ruined the drywall, even though I had locked it tight with the supplied wrench. I had success ~80% of the time, but that's not good enough.

Rated 5.0 out of 5.0 by tcope Good product. Must have for multiple holes.
Cut 12 holes for recessed lighting. Needed several different size holes so I went with this device. What a time saver! It does just what it is supposed to do. Works great. Some advice on use... make sure you have the cutter level or it will gouge the drywall outside the hole. I'd recommend tightening the cutters every 4 or 5 cuts to make sure the hex nuts are not coming loose. Do not cut too far into the drywall or you will also gouge the drywall outside the hole. Cut into the drywall and then back out a little to see if the cut hole comes down. If not, cut a little more until it does. It's better to remove the cutter complete and see if you are through rather then go too far.

Rated 1.0 out of 5.0 by JPena Not strong enough
This unit is not strong enough to get the job done right. I bought it to upgrade my kitchen lighting and after the first hole, the small blades broke and once that happen you are out of luck. Also the screw keeps getting loose every time one turns it on. I would not recommend this product.

Rated 1.0 out of 5.0 by 123abc Broke on first use.
Dust still flew everywhere. The adjustments only go by the 1/2 inch so the measurement was off a bit. The set screw came out from the vibration so the adjustment went to the biggest size which meant I had to replace the drywall and start over. Nightmare of a product.

Rated 5.0 out of 5.0 by JamesB Works perfectly!!
I brought this to install 6 cans in my living room. It made perfect circles nice and clean. Tip.. Don't use too much pressure and let the tool do the work.

Get this tool for can lights. It's the cleanest easiest way to go.

works very well when installing recessed can lights, just have to get use how to hold the blades slightly off of the drywall so it does get stuck. Almost scraping the drywall wall, which gives you a nice clean cut.
