. Unfortunately, after reading the review, I decided to return it. First, the buffs I usually use have a feminine finish. This device appears to require a threaded male end. Then, after attaching the included wheel, I found that it wasn't that easy to remove. Another buffer I have has a stop/lock button to lock the shaft and release the wheel. This is not the case as I had to stick a small screwdriver through the outer hole in the right place to block and remove it. It worked well with controllability, but due to the design issues mentioned above, I decided it wasn't the best auto-detailing option for me.
