  • getting used to (new kind of tool)

I have owned the product for some time now. It took some getting used to, partly because I'm not used to such an article when you compare it with the traditional "tools". Pleasantly surprised about the applications and results. Very handy device that is easy to hold. Easy on the flow and go. Many different attachments to use.

All in all, very enthusiastic, with an indispensable tool for the real handyman.

  • Can my wife do more jobs now

I'm getting more and more attached to my Dremel. What once started with the purchase of a multi-tool from an unknown brand, has been converted into the purchase of this Dremel. This after quite a lot of frustrations with the previous multi-tool. Yes, it was rechargeable, but the power and smoothness of this wired Dremel is amazing. It is precisely those jobs where a jigsaw, circular saw are much too big to use. Or simply because there is no other device that can get the job done. For example, I just installed a cupboard wall where the plinth (made of wood) had to be shortened. It's already on the wall. No idea what other device could have shortened it to the right size. Or think of new sockets. These had to be replaced at some point. The Dremel made sure that the stucco that was around the old sockets was expertly removed so that the new ones fit nicely. But also remember the screws to secure the interior. These were way too long. Ideal for shortening them with the grinding wheel. Tried previously with a hacksaw. Give me the Dremel. Pros: the large amount of accessories available (although you can do a lot with the supplied accessories), the power of the device, the solid quality and definitely the SpeedClic mounting for some discs. Ideal. Are there no drawbacks? Yes, some people may indicate the price. But that's relative. I have now previously spent money on a cheaper model that I will never use again. Good tools have their price. If you spread this out over the coming years and the pleasure you get from it, then it's not too bad.
