Does the job. Price/performance spot is right.
As the photos show, it did a perfect job cutting a 6 1/2" hole in my new cielling of 1" thick tongue & groove pine boards for new low-profile/flat LED recessed light fixtures. I cannot say anything meaningful about longevity of the hole saw, like many here in the reviews, I just have this small project of the cielling with 5 lights to do. After that, it's going to get put away for future need thar may never come. Or get lent out to a relative someday. However, 1" thick pine is a tougher challenge than the drywall the majority of people will likely use it on, and it did the job well. And checking around, the least expensive alternative in a local retail big-box home improvement store was $7 more. And it was the flat carbide "bumps" type that's better on drywall or tile, and difficult to use on wood. And it's no different as it is made in China too. My only significant advice is that big & wide hole saws, no matter the brand, put a huge amount of torque on the drill. And if they catch, stick, or kick in what you're cutting, they can twist the drill very SUDDENLY and very HARD. This can knock you off a ladder. Or posibly twist the drill so the battery box slugs you right in the jaw, as hard as a decent boxer's punch. If you haven't used one before, it's really worth 10 minutes of time to practice on a piece of scrap board similar to what you plan on cutting the hole into. It's important to get a feel for how the saw behaves on the drill's "Fast - Drill" and "Slow Hi-Torque" settings behave. Plus, it's good to have an understanding of how important it is to keep the saw level and square to the surface you're cutting. Because angling it unintentionally is what will make the teeth on one side dig in, stop the drill, rip it out of your hand, and make it slug you in the face. And, if your drill has a side handle for an extra 90° hold, use it.

Worked great, did the job
This worked for my use case, and saved me a lot of money instead of buying a name brand one for 50 dollars after you add in the cost of an arbor. I cut 10 wood holes for cup holders on a poker table.

Very Sharp
I bought this ITOOLFIRM hole saw to cut through drywall for old-work ceiling pan electrical boxes. I only had a couple to install, so I went with this less expensive one and was really impressed. It cut very clean holes, surprisingly fast, with zero kickback. The drywall plugs even released with just a few taps. If you need to cut a 3-5/8” hole, this is the perfect saw.

OK Value for the Money But Doesn't Perform Like a Milwaukee
We needed to drill a few 4" holes for a new radon abatement system and for 3" toilet drain lines. This blade worked flawlessly cutting through the wood and siding with ease. The blade is thick and sturdy enough that it doesn't flex like some cheap alternatives. It was easy to use and swap out between drills and clean out slots are big enough that any plugs left inside the hole saw are easily removed. I took away one star because when this was used to cut two pieces of 1/4" cement board the blade dulled quickly and barely made it through the second piece. It still cuts sheetrock well but now takes more effort with more binding when cutting joists.

Weak drill bit, nice saw
Drill bit broke on first hole, it was soft aluminum, the actual saw seems like good material though

I used this for cutting 3” holes in wood to install soffit vents. The hole saw had a fast cut and worked very well for me. The arbour also fits hole saw bits I currently own, which was a bonus.

The price is excellent, and the drill insert is sturdy. I use it with much larger hole saws without any issues.

Used to install soffitt pot lights. Worked great. Remember to start in reverse to cut a groove and then switch to forward. Much better price than box store. Even if it doesn't last it cut *8 holes for me nice and clean.
