it wont screw on all the way but it works so its fine by me
The remote switch works OK, fits the the torch perfectly, and is very massive. There are two buttons - one is an on-off just like the regular tailcap, the other is a momentary switch without no fixed ON. The on-off is working well, but the momentary is not reliable. The whole assemble is exactly as on the picture, just bigger than I expected (my wrong).
