I wanted a cheaper flex shaft than mainstream brands (Dremel and Black & Decker charge significantly more just for their name). This one definitely works very well - more or less the same as this one I'd say. It seems to me almost as strong and all, so I think it will last more or less the same amount of time. It definitely fits standard rotary tools easily. I think it might vibrate a bit more and doesn't seem to work as well with some of the bits made for rotary tools, but some of the bits officially made for them are really meant for a much larger device with more mass , so shaking them doesn't affect them that much and they only upgrade to fit them when they really probably shouldn't. : their use of a non-standard "key" to actually change the bits. Usually these things use a small knob that you hold while twisting the piece at the end to hold the shank in place. I'm sure this method is cheaper and theoretically more durable (although I haven't had this nozzle breakage on any of the ones I've ever used), but such a "key" is almost 100% guaranteed to be lost. I had to glue it to the end of the flexible shaft. But eventually it falls off or I forget to put it back on and it gets lost. It's not even the usual default "key". I suppose a hex wrench will still fit, but it will likely be a little loose and a little more difficult to use as a result. It works great but I really wish they hadn't gone for this particular design. The default "button" method has always worked well and would continue to work here.
