Can’t use it if it doesn’t come with all the attachments you need for your model. Literally none of the pieces that came in this box fit with each other let alone my tool. Complete waste of money.

works really well and cuts easily. just make sure you tighten the guide tightly or the guide will wonder and you'll end up with an oblong hole instead of a round one

I needed to mount my portable air conditioner hoses in a large piece of Plexiglas and already owned a roto zip rotary tool. This inexpensive attachment was just what I needed. It is adjustable and worked great. I cut 4 holes and the fixtures to mount the hoses to fit great. I recommend this product.

I read a few reviews saying this was too flimsy, but I needed something for a single project to cut a 4 inch diameter hole in plexiglass and wood. I tried to build something myself which was a dismal failure, so I bought this. I have the Rotozip Pro Classic. This tool worked great and was just what I needed. I had a little trouble getting the adapter onto my Rotozip, but once I pushed it in the correct way (towards the tab), it worked fine.UPDATE:I'm downgrading this to 3 stars. This time I needed to cut an 11.5 inch diameter hole in 3/4 inch plywood. I made the hole in test 1/2 inch plywood first to make sure I got the diameter right. Then I started in on the 3/4 inch. It was a lot harder to push through, which is fine, but about 3/4 of the way around the circle, the adapter slipped on the tool from the pressure. I didn't realize it at first, but what it did was cause the Rotozip to cut right through this adapter, metal and all. (See pic).So, for making a hole in drywall, plexiglass, or 1/2 inch plywood, it's fine. But anything thicker, I recommend you do what another reviewer posted: make a donut out of sandpaper by gluing two discs back to back so that the rough side is out. Then place this in between the pieces of the adapter so that it won't let them slip apart when the going gets tough.Also, even with thinner material, you have to be really careful to apply the same kind of pressure both downward and outward. If you stop to switch hands, you'll get something like my second picture. The best is if you have room to completely walk around your work piece as you cut so that you don't have to switch hands.

This jig works just fine if you take your time. I read lots of reviews about use and cutting through the metal guide.Regarding getting started, don't try to plunge cut at the starting spot. Draw out where your cut will be, drill a hole at the center of your circle, drill a hole where the blade will go and insert the tool powered off. Then when your set turn it on and let the blade do the cutting not forcing it and you should be fine.I was cutting paneling so wasn't very thick, but I held the tool and knob of the jig and gently moved through the material. I think if cutting thicker and start really forcing the tool that's when it seems it may slip and cut the jig.So, be patient and you'll probably be fine.One complaint I have is they give you a set screw that was only about half as long as the one my tool has, so that was garbage to me, used one I already had.Also, the instructions were not well laid out and didn't give instructions how to get the hole started as I did above, so I can see how some may not be sure the best method of usknf the jig.

I cut some 8" holes in hard MDF and soft fiberboard and cardboard (practice runs) and it was easy to use and cut accurate circles each time. Remove the rubber cover from the center pivot tip before use. Drill a 1/8" hole at the center point in your material and place the tool's 3/4" long center pivot tip in the hole. The tool does not lock on to the material, you have to hold the tool in the pivot hole while drilling. This is usually not a problem because you'll have one hand holding the Rotozip on the material surface and the other hand will hold the tool knob (which does not spin) to help spin the tool. You may be able to use the tool with one hand just on the Rotozip if the material surface is smooth.One possible improvement would be to replace the center pivot with a spinning threaded rod. This would allow the tool to be bolted to the material. But it's a fine accessory as-is.
