I wish I had, had the opportunity to actually use one of these that had seen extended service before I actually bought one.
For the first few months the Sonicrafter worked OK. Then the mediocre workmanship started to show up. I sent numerous emails, and made several phone calls to Rockwell. They never answered or returned any of them. In desperation I called the sales number on the infomercial. The sales rep took all my information and said I would get a call the next day. Needless to say I did not.
In brief my problems have been as follows:
1. The Allen Screw that secures the blades now vibrates loose, as a consequence I had to stop to re-tighten the blades every few minutes.
2. The front end gets VERY hot. I mean hot enough you can't hold it! It will deform thin plastic sheeting such as the vapor barrier on wall insulation.
3. The blades are very poorly made. They dulled quickly. I don't know what kind of blades they use for the demonstration videos, but it certainly is not the same as what they sent me. Certainly the nails they show the unit cutting must all be cheap non-ferrous metals.
4. The owners manual that came with the unit must have been written by someone for whom English is a second language.
Supposedly there is a two year warranty on the product. Good luck getting Rockwell to honor that. They essentially have no customer support to whom you can talk to get a RMA number or arrange a replacement.
As a result, my unit is now an expensive paperweight. It does have one useful purpose. I show it to my friends and associates to let them use it if they are thinking of buying one. After using it no one I know wants anything to do with this product.
I ended up buying a Fein Multimaster. More expensive? Certainly. But I only had to buy it once, and it works as advertised. You do in fact get what you pay for.
In summary. Initially the Sonicrafter worked as advertised, but it did not hold up to long term use over a 3 month period. My personal feeling is that the high heat generated by this tool coupled with the high frequency oscillations were more than the cheap materials used in building it could stand when used over time. This may work for a hobbyist making wooden models. but for serious work, it just did not stand up. Customer service was oriented at making sure the customer has no way to actually exercise his right to use the Warrenty.
