I've just received one to replace the Cyo that snapped of its mounting last weekend. I've not fitted it to the bike yet, and the instructions warn against powering it with DC, so I've not lit it up with a bench supply.
Initial impression is that the aluminium body is neat and sturdy, the lens reminds me of the original 60Lux Cyo, and the plastic bracket looks decent, but should be replaceable with a standard B&M wire one if it turns out to be made of cheese. The trailing connections for the rear light are very short and hide inside the bracket, which is lovely and neat if you haven't got one. The button is clicking on a standard tactile switch, with the ring of translucent silicone that forms the status blinkenlight forming a seal. One thing I note is that unlike those with a switch with distinct mechanical positions like the Cyo, in its completely unpowered state you have no way of knowing whether it's switched on or not. Presumably this will be less of an issue when it has standlight power.
Interestingly, it has a BS6102/2 marking in addition to the K1192. Oh, and the supplied bolt-on reflector looks like an afterthought, but will probably work okay if it's not bashed. Now, where did I put my crimp tool...
