Rotozips..... I got one way back when they first came out and were a big deal for Christmas..... well I got mine on sale in Feb. of that year for my B-day. It was without a handle and didn't have much power but I was doing a bit of sheet-rock work and it was nice to put the outlets and such in.... made a mess but did a good quick job. It also got very hot after using it for a while, like hot in this is not confortable to hold. I found it needed to rest between jobs. So if you have one of these you most likely didn't like it, I know I didn't.
A couple years back they had a deal I couldn't pass up with a new more powerful one that had a vaccume attachment, circle cutter, would take 1/4" bits and all packaged in a plastic box. This model was a lot different, had a handle to hold and maybe double the power. I picked up the plunge base for a project I was working on.... free hand thru lettering on some cedar.... Let's say it is not a router..... I have used it to make speaker holes, masks for painting, a few remodeling projects and I'd say I am still not impressed with these.
They work fine in drywall, celotex, 1/4" this and that but even in 1/4" wood they are no match for a router. I think it has more to do with the bits they sell then the tool, from my experence you need to buy the big bag of them or they make a big dent in the pocket book as the bits don't seem to last to long.
Now maybe they have a new and improved one out now or better bits???? I'd like to here from somemore people that have these. Or maybe someone has some knowlege they can pass on about how to use them?
