Pat B Very nice light. Impressively bright, will get a second one for my other bike.
Glenn Bright!! So bright. Fits nice on different saddle posts (different size connectors). The several modes of light are very useful. I use the lowest light blinking mode to extend time....and it is more than bright enough! Great light.
Mr Roberts Great light. Easy to set up. Multiple rubber mounts included depending on which size seat post and where you want to mount this light.
Mr HB I use it for day time. Low flashing mode has a good battery time yet enough brightness for most.
Mr Fieldhouse Light is what I was expecting but I do not like the Velcro strap to fix it to the bike much prefer the fixing on the previous model
NivramKSA No problems now riding at night with this super rear light. Love it!
Ed This light works nicely. The attachment mechanism (O-rings that stretch around the seat tube) seems a bit weaker than screws or rubber sockets. I would prefer another attachment mechanism if I were taking my bike off the road.
Currie Cracking light which pumps out alot of light. Fits nicely on the back of the seat post and is very aero. The only thing I didn't check was the size - it only just fits between seatpost clamp and the bottom of the saddle. Obviously an issue specific to my bike but worth checking as you can't change the mount to turn it horizontally. Hopefully this light will last longer than others lately but I'm impressed so far!
Mr Fairbanks Fits easily and securely but easy to remove. Bright with enough options but seems a little slow to re-charge
Mr Tan Good for visibility, great little gadget. Battery is only 500mAh but what can you expect from a small light.
Pitpilot The light is nice and bright, the only downside compared with the previous model is the ease of taking it on and off the bike for charging.
Jonathan Easy to put on and take off and can crank it up to a really bright flashing mode. Great back light
