Just got my hands on the Neeki Flapper Adapter and wanted to share my thoughts. First off, the build quality is solid—stainless steel feels sturdy, and the machining looks precise. Came with 3mm and 6mm collets, plus a wrench and a wooden dowel (nice touch for removing tools).

BUT here’s the catch: if you’re in the US like me, you’ll probably have 1/4" shank tools lying around, not 6mm. The listing *does* warn about this, but it’s easy to miss. I tried forcing a 1/4" tool in—bad idea. It wobbled like crazy. Seller suggests buying a separate 1/4" collet, which feels like an extra hassle.

On the flip side, when I used it *correctly* (with a 6mm-shank wire brush), it worked like a charm. Turns my angle grinder into a makeshift rotary tool—pretty versatile! Just make sure your bits are rated for grinder RPMs (safety first, folks).

Wishlist: Include a 1/4" collet by default. For now, docked one star for the extra hoops. Still, if you need this functionality, it’s worth considering—just read the fine print!
