Mr Inui good
JJ Very bright and good price. My second purchase
Tom Excellent tail light, comes with many mounting options, highly recommend
Steve Great light, best I`ve owned. Lots of mounting options , very good quality .
L davidson I`ve always had trouble getting a decent rear light that works - that was until I purchased this light - it is amazingly bright + the battery power is good, does it exactly what it says on the box. Great buy.
JohnK Good light with plenty of lighting and fixing options. I`ve been using it on daytime flash using the belt clip to a bag. Good battery life. The switch is just a bit fiddly with gloves, but not a big problem Good price and usual excellent service from Merlin.
Mr SAWFORD Smallish neat light fits well on my aero seat post with a good bright LED bulb so I can be seen when riding at dusk.
Barry Small, light, very bright and versatile fitment.
Lars Great lantern that makes you visible from behind. I really like the way you put it on your saddle. Has different modes and brightness.
Mr Razvan After the reviews of this item find on google, I had to try it. And I'm very glad I did. The product has very high quality materials, the light can been seen from a wide angle and it is very powerful and pleasant too! Definitely a must try and have product. Thanks Merlin for you're service! (The package has arrived in 3 days, very fast considering that I'm from Romania)
Mr Rajala A versatile & professional rear light. I really like the saddle rail mount that came with it, it's sturdy and aligns the light perfectly. The light itself has enough power for any use I think. Burn time seems to be adequate at least in low & mid setting. The light has not let me down even once (Finnish winter weather, everyday city use). Great value for little money.
Mark H Great product.. easy to install and its super bright even on the lowest setting. The highest setting is like a camera flash! So you won`t have to worry about not being seen. Parts and actual light all feel really high quality
Mr Fernandes Very satisfied. Even with minimum intensity, the cars when approaching give much more room than before.
Steve Costigan Great little light, comes complete with saddle rail mounted bracket-perfect for a reverb seat post!
Shane The first time I used this product, cars seemed to give me a wider birth. It is 5 times brighter than the back light I already have. Excellent product
Rich Tong What a great rear light this is. Well made with loads of functionality and mounting options too. I went for the seat rail bracket, which was a doddle to install and keeps my seat post clean and aero. For the lumens it emits it weighs a feather too. No water ingress after several wet rides and Merlin's sale price was cheapest by far!
Mr Atkins Compact but very bright and a good price. Easy to assemble and install and gives a little more confidence on the roads.
Ms barfoot Great light, very bright and fits onto the seatpost without any tools, uses an O-ring type device to do this. Would recommend.
Mr Jackson This an excellent daytime safety light. Very bright with a long run time on the daytime flashing mode. Very light and unobtrusive, with an excellent clamping system, which adapts well to handlebars, stems and even forks!
Mr HARTLEY This is my second "moon" rear light, and the "Comet-X Pro Rechargeable Rear Light" is a step up from the last "Comet" rear light for sure. It's small enough to tuck neatly underneath your saddle, (and if you turn the under-seat mounting bracket upside-down, then the light is totally unobtrusive, and a saddle bag fits as though the light wasn't there). This light is super bright in both constant and flashing modes, has a great battery life, and weighs virtually nothing. Worth the full RRP, but an even better buy when on offer at Merlin Cycles.
Mr LAU Great that it includes a saddle mount, but preferred the more simple design of Comet MK II where you can just wrap is around a seat post without an additional bracket. Also, would like to see a lower output on the lowest setting for group rides, it used to be 6 Lumen, now the lowest setting is outputting 15 Lumen already.
Mr Robb An excellent rear light that is bright and easy to attach. Several attachments are included to enable you to locate the light according to your preference. Light provides several modes re brightness flashing and riding time
Jason An impressively bright and compact light. Battery life seems decent on the "flasher" setting I have been using. There are numerous modes of operation to suit your needs. I can't really comment on long term reliability yet as I've only had the light a couple of weeks and it hasn't seen any wet weather.
