Nicholas This is the second one I have bought of these, to add to another bike. Great product.
Alex PM Lovely light - good range of lighting modes and appears to be well made. Seems to be bright and the bracket fitted an aero seatpost, Merlin cycles ordering process was fast and efficient.
Mr Henley Excellent little light! Decent amount of modes, very bright and easily visible in daylight and decent battery life. Well recommended.
Prof Castro superb, great quality for small price. visible from miles away
Mr rose Small, easy to fit, and really bright 👍
Jervaise Needed a light that fitted aero seat post.
Mr Talbot Bright, portable & good battery
Colin Very pleased. Lightweight and good visibility as commented by riding group. The belt clip is especially good with a barb to stop accidental loss from slipping out. Not sure about aero bracket?
Mr RODGER I wanted to mount this on the chainstays as a second rear light and the fittings work well for this. Good bright light with all the settings needed, but I only just purchased it so I don't yet know how durable it will be
Taz This is a lovely 'be seen' tail light. Simple, functional and attractive. It's easy to fit on the seatpost and easy and quick to charge via a micro-USB cable. There are several fake versions of this around so be sure to buy the original Moon Ring version. The light output is nice, sharp and bright. There is also adequate side illumination.
Christine Very bright and great fittings too.
Daisy Great light, very bright, very easy to fit on the bike, a great buy.
Sean Mc Originally purchased this light as an interim measure until I could afford a better one. When it arrived and unpacked, the size left me a little underwhelmed but the build quality did feel really good. I used the bag clip on my Topeak under saddle and found it to be very secure, almost difficult to get off even when you wanted to - another positive. Finally tested on my morning commute at 4.30am and found that this little light really belts out some brightness! With an easy access power button and USB recharge this light really stacks up well, so much so, that I have stopped saving for a 'better' one and get to use that cash for other goodies : Well impressed - thanks Merlin Cycles!
Timothy This was a replacement for one which worked well for 2 plus years. The old one died because I did not push the seal down well enough over the recharge point and it got contaminated. Bought same again. Good for aero post on Venge.
Roger Excellent product. Lightweight, good battery life (for its size) and many fixing options included.
Mayfield Works well; I ride my bike to commute across town and I'm confident that my visibility is much higher now that I have this bright little circle on the seat post. It comes with several blinking settings and a solid light setting; so far I've been able to ride with it on for two hours (cumulatively between rides) without needing a charge; I haven't yet needed to charge it since getting it. Another aspect I quite like is that the mounting system is easy enough to take apart, or I can just remove the light itself whenever I lock up my bike. I'm not sure whether it's a pro or a con, but this is much smaller than I was expecting. I was expecting it to be about twice the size it is; the light is about two centimeters in diameter. I have yet to ride with the light in a truly pitch black setting, seeing as how there are streetlights for most of my route through the city, but the most important thing is as I said: cars can't ignore me as easily.
Mr Alner Very bright and well made. Stands up to a lot of wet and mud on the back of my fat bike. Easy to charge with the supplied USB cable and the charge lasts for ages.
Fuller Wasn't expecting much due to its tiny size - but whoa its bright and flashy! - impressed plenty of mounting options too. Great little rechargeable light.
