"Unacceptable design flaw"
- Reviewed By An Amazon User from USA
I like these oscillating tools, and having a need to purchase a new one after the death of the motor in my Dremel Multi-Max, I decided to give this one a shot. I was initially attracted to this device due to it having a more powerful motor than found in the Multi-Max, and considering that's what died in the Multi-Max I figured this would be a big plus. I'm having Dremel repair that dead unit, so I also figured that having both models would give me a larger portfolio of attachments to choose from as jobs came up.
So I bought my SoniCrafter Rockwell and then returned it within an hour of that purchase. It turns out that the designers failed to take into account that the blades would be vibrating. A lot. The connection between the device and the blades was so poorly thought through that within 30 seconds to a minute of use the blade is already loose and wobbling around. I used my Dremel extensively over the past year and this was a problem I didn't encounter one time.
What's the difference? Blades attach to both units using a bolt that is tightened using an allen wrench. With the Rockwell the blades have a large hole with 12 (I think) points that lock into something similar to the top of a 6 point bolt head. Whose bright idea was it to use a different number of points? Had the points been the same in number the grip between the two would have been much tighter. Aside from that, it doesn't take much use before the blade slips from this grip and wobbles around. The Dremel Multi-Max, on the other hand, has about a dozen small teeth that poke through small holes on the blades and this eliminates wobble so well that I never had this problem one time. Obviously the Dremel engineer was awake during this stage of the design.
This is a problem that would have become apparent on day one of testing so why wasn't this problem fixed before bringing it to market? That's one of the things that bothers me the most: they must know about this and just don't care to fix it. I'm so sick and tired of buying products that give all appearances of being good only for their to be one big problem that ruins the entire thing.
"ITS NOT A FEIN"

It's not a Fein but for what I needed it to do it worked out perfectly
"Sanding attachments are very poor quality, wear out quickly!"
- Reviewed By An Amazon User from Denver, CO
Unlike most of the previous reviewers, I use this tool mainly for sanding in tight spots that my other sanders won't reach. The Sonicrafter has two attachments for this, namely a triangular pad and a smaller sanding "finger". Upon initial use these pads and the tool did the job very nicely indeed. However, I quickly found out that the backing and hooks on the pads wore off (!) after about 15-30 minutes of use. The problem seems to be that the pad itself (which seems to be some sort of rubber or plastic) can't take the heat generated and thus quickly melts, burying the hooks into it and rendering the attachment inoperable. The first time that this happened I bought the "heavy duty" version of the sanding tongue, only to find out that the lifetime of this was even shorter, maybe about 5 minutes of use! Clearly these attachments have to be re-engineered for this tool to be useful as a sander.
"Good deal for the price, but has some problems."

I researched every brand of these tools before buying a refirbished one. It works well and I use it a lot but the screw mechanism that holds the blades on really needs a better design. The end does get hot but its not unbearable. Be prepared to buy more blades.

I was leery of this product at first since it looked too good on the TV ad. It's a sturdy device that does everything the ad says. I'm really impressed. This turned out to be a very handy tool for the house and garage.
"Great Christmas Gift"

Got this for my husband for Christmas. We are building a new house and so far it has been very handy for some small projects. The real test will be when we lay the travertine floor. For now it is very handy for the wood projects.
