UPDATED REVIEW MARCH 2023: All of the stories about Avid's outstanding customer service are 100% true. The company stands completely behind their product and is extremely responsive about fulfilling warranty service. I purchased Avid's multitool in March 2021 and had exactly one week left on the warranty when the multitool abruptly refused to turn on. I reported the issue and got a reply from customer service the same day. They asked for a video documenting the failure, which I did, showing that it wouldn't turn on from an outlet that was shown to provide power. Avid sent me a brand new replacement unit in two day's time, and now I can finished my job. Avid's tools are functionally quite awesome and it is so great that they stand completely behind their products. I respect a company that does exactly what they promise, no more and no less. I will be a repeat customer.

ORIGINAL REVIEW: This is a powerful, sturdy-feeling oscillating multitool that should be in every homeowners toolbox. It comes to the rescue for some many ad-hoc renovations and repairs. I was trying to jam my jigsaw into a narrow space to trim some shims around a door frame without success, until I realized that this multitool could perform the same function much more easily. It's narrow enough to work its way into many different nooks and crannies, and it cuts through hardwood like butter with the included blades. As a sander, it is powerful to the point you can use it for decently sized jobs.

The Achilles' heel of this tool seems to be that it is prone to dying without warning: I used mine lightly for a few odd jobs, and this morning it quit mid-job when it wouldn't turn back on. I don't know if this is an issue with an internal fuse or something else, but from reading the reviews it seems like a variety of people are reporting the same behavior. It would be nice if there was a way to service this ourselves if it is something simple like a fuse. I am just within the window of allowable warranty service, so I will reach out to the company and update this review with contact information for the company (which is surprisingly difficult to find) and my outcome.

I bought this for one specific job, thinking it would be a throw away at that price. I usually only buy Milwaukee tools for their quality. This thing is amazing. I had an entire day of cutting out a glued section of fiberglass on my boat, having to cut through some nasty adhesive, stainless screws and fiberglass - took about 7 hours of non-stop heavy work. I can't stress how good this thing is for the money. It feels like a solid, well built tool. The quick change blade system worked flawlessly. I purchased carbide blades for the project, and I'm glad I did. I tried a couple of the blades that came with it, and they would be fine for wood or softer materials, but I went through 3 of them on my project before I gave up on them. I would definitely recommend this tool to anyone. I would put this up against a Fein or Milwaukee on any project.

Easy to use and very versatile. Used for sanding drywall, wood, metal. Cut small wood & metal items and PVC. Nice go to sound the house. Easy on the sanding loop sandpaper can come loose and ruin the heads. I have replaced 3 already (get replacement heads with purchase of sandpaper)

This unit was a good balance of price/features. This should be the "go to" tool for most homeowners. I'm still finding ways to use it. Gets in to places where a sawzall can't, and a hammer/chisel is too brutal, or may add collateral damage
