Mr WigstonExcellent light. Bright, easy to install, lasts for hours. Recommended
RSGNot Moons best light. The MKII is significantly better and worth the extra expense. This becomes extremely difficult to take off due to the fiddly attachment mechanism. I love Moon lights, but not this one.
Mr WallisBright simple to use - secure on the bike although the mounting seems overly complicated
PaulBit smaller than expected but good bright light with a few different brightness settings. Lots of different fixings included in the box, including belt clip, which was one of the reasons for purchase.
Mr DuxburyBrilliant compact and bright light. Plenty of display options for safe road riding. Easy and secure fitting. Well worth the money.
Mr letchfordBright, long lasting battery.
Mr MacEwanDoes what it says on the tin. Extremely bright, battery lasts ages.
Mr OliverA super easy to use product. I keep it in my pocket and clip it on whenever the light fades a bit to give me extra visibility on the road.
Mr MCLEESESo far this is the only light that I've tried that actually stays in position on my aero seatpost. Plenty bright enough too.
NoddlessBright and long lasting
Mr CrossenGreat little light. Nice and bright and I like the mode options it comes with. Easy to use and the power button is tactile enough to feel through gloves.
DerekNo complaints, does what it says very well and great value
Mr HeffernanVery bright light , definitely will be seen. Delighted with Merlin’s quick delivery
Mr JordanWorks really well, simple to use and nice and bright
BenGreat light at the discounted price so I bought two. Good light output can be seen from the side too. Quick recharge time and nicely thought out attachments.
Ms SymondsFantastic product. Incredibly bright, options and quick to put on and off your bike. Long lasting between charges. Really pleased.
Mr GNot as powerful as the front light, but still pretty powerful in a small package. Mounting is very adjustable to any angle you attach the clamp to to get it horizontal. Flashing and static modes fairly powerful and easy to use. For the price though they are very good.
SalimGreat light & very visible, battery last for really long time
SimonLove these lights. V bright and easy to use. Now have them on all our bikes.
Mr MikkelsenNice mount - very bright light!
Mr GilbertVery bright and visible from a wide angle
Mr McCallumEasy to use and charge. Meets my requirements fully!!
Howie D (AKA: CF_Racer)Would not fit the "D" shaped seatpost of the Tarmc SL6 but came with a belt clip that clipped on my saddle bag clip and works great. Very pleased. Bright, many flash modes, runs for hours.
Mr MerckxSuperb in every way. Charges quickly, very bright. I use it as a daytime safety light; it’s still flashing happily after a full day out so battery life is good enough for me. Seems reliable too.
Jay-vErgonomics and functions was fantastic.
EmORear light is really bright! Clasp is adjustable so will fit all kinds of seat-post.
Mr McGillyMan these new LED light are so bright. Not like the old AA ones. Good fit you can tilt it to be horizontal on seat posts. Lots of different brightness and flash options
Cardy GeorgeVery bright, lightweight. Steady mode had distinct differences in output, but I can't detect a discernible difference between flashing patterns.
Mr WilsonSimple affordable with a good mount and easy charging
MansonGreat rear light. Has a good bracket for aero seat post which I wanted.
Mr FieldhouseLight is great, nice and bright my only gripe is the fixing, I don't like the rubber band system much prefer a permanent band.
