I bought this product to use with my polishing wheels on my motorcycle.
It is well made,and good length, with the added bonus of the drive shaft running in bearings. So with an occasional lubrication the flexible drill extension should give me a long service life.
Overall I would recommend.
Well made item with long reach and 10mm chuck.
Used it to cut through a hard to get at water hose clamp on engine.
The RPM of a drill is not as fast as a Dremel.
