Yep – I’ve got one. The real USP is the remote switch. Like on a motorbike – high low beam. Great for commuting and towpaths etc not to blind folk. I’d still use mine for that.
Light wise they are slightly better than the original bastid. With a broader beam on full tilt.
Now for the down sides: that price is really really expensive. I paid around £60 1 or 2 years ago and it should be cheaper now.
Also the head unit is too heavy for its mounts. You will (inevitably imo) modify it to have a sturdier mount. Though this is easy enough and cheap enough though.
A much better bet imo are : for throw – an XML light (like smudge sells) for less £ : or for flood – a 4x (or a 3x) XPG for around the same cash.
