I've decided that it is worth adding reviews of items that I have purchased and used. Reviews are independent - I'm not on anybody's payroll. If you have a review of any bicycle-related item, let us know via the forums and we'll consider publishing it.

As listed on the seller's website:
The Fenderbot™ tail light is a rock steady safety signal designed to make you more visible. It's equipped with a precision reflector and super bright red LED.
The Fenderbot™ bolts directly to your fender to prevent theft, so you will need to summon your DIY skills and drill two 5mm holes 20mm apart on your fender.
I do rather like this light. Drill two holes in your rear mudguard/fender, mount with supplied hardware, and away you go. A nice feature of the design is the small screw which makes it easy to replace the batteries without having to pull the whole light off your mudguard. At a mere 62 grams, it isn't likely to cause any load strain on lightweight plastic mudguards. I find the various dancing patterns offered on many tail lights today to be extremely annoying if you're in a group ride behind one of them. Worse still, as a driver it is all too easy to ignore a dancing pattern light and fail to recognise that there is someone on a bicycle there! PDW have been most sensible in offering two modes: Steady and Flashing. I like lights like this.
What do I not like about this light? Well, to be honest, it doesn't appear very bright unless you're looking straight at it. I would have gladly sacrificed a little battery life if there was one very bright LED in the middle and two small ones facing outwards a little to throw more light out. That said, it is still quite an effective little unit that does its job without fuss. I say get one. Get one for each of your bicycles so that you're never stuck in a situation where you have to ride at night without appropriate lighting. I give it 8/10.
