A functional adapter with some flaws. It does it’s job for providing a 3rd party adapter for glass accessories. Be sure to tighten just enough to secure in place and no more. But be cautious of the fit, as the tolerances on the Mighty & Crafty are pretty tight. Required a bit of sanding of the underside of the glass base to fit both devices correctly. A bit of sanding with all surface fine grit sand paper and a thorough cleaning produced a much better fit. Research showed that others had cut down the plastic base, but found this to be more difficult to attempt given the small size of the plastic adapter. Quick shipping and great protective packaging. This product will work, but there may be better options.
