Comments

karen bryant: I purchased 2 of these in April 2023 and by October 2023 both would no longer power on even with fresh batteries. I'll be replacing them with something more high quality. Really disappointed because I really liked how they worked and looked when they actually worked.

Dr. Wyre Moore: The unit installed easily and worked for about 10 riding hours, passed the return window. I contacted the mfg directly, and they were very responsive. The unit was promptly replaced with a usb version

I highly recommend the usb version

There were problems with the battery version, which I missed in comments and feedback. My fault.

Aldo highly recommend this mfg for their support and integrity!! Overall would buy again, the usb version.

MJMJ: First of all, their customer service is stellar! Had an issue with the first one, and they immediately sent out a new one. No long drawn out process or hassle, just fast action. Had the replacement within a few days. As for the light itself, outstanding! Super bright, easy to install and operate, and great battery life. Very happy with my purchase, and especially with this seller. Highly recommend both!!

T HayneT Hayne: Seems pretty well made. Looks bright when light is on. Does the brake light function work? I may never know. It is on the back of a motorized tandem so I can't see it activate. Installation was tricky. I had to get creative. MOST bike racks do not have the 2 hole mount that this requires. I used strapping that usually holds up ductwork.

Kron: Problèmes:
Montage difficile: les vis disparaissent à l'intérieur du boîtier avant d'être touché.
Le bouton allumage introuvable dans le noir, de plus une fois retrouvé exige une pression forte pour actionner.
Etanchéité problématique

Garry Lash: easy to install, very light

Ben VeenkampBen Veenkamp: I bought this light more for it's ability to indicate to people behind me that I'm braking and it works really well. It's very reflective when not turned on so when the "brake light" appears (and it does) when I'm coming to a stop it lights up bright enough for day and night. It fits perfectly on my rear rack with no protrusion. It just looks as though it belongs there.

It would have been nice if it was USB rechargeable, but then I suppose having to use 2 x AAA batteries instead means the light will probably last for years longer (ie: I won't have to throw it away when the rechargeable battery doesn't hold a charge anymore). I read a couple of review about the batteries popping out when going over a bump so I just used a little gaffa tape over them and that works well.

S. Tucker: I've had this light a few weeks now and I ride everyday at least 5 miles for work. I was concerned with the quality level but so far it hasn't broken or popped out of the bracket, it might still do that. It's light but not that study. The light replaces the standard reflector that came on my Giant ebike rack/battery mount and so it's visible when I put cargo on the rack, which is why I got it. It fits perfectly and is basically the same exact size. I use rechargeable batteries and it's easy to remove half the light to swap batteries but it could end up breaking or falling out after repeated daily use over time, maybe not. The batteries don't stay in the tray, the roads I ride are paved but lots of bumps. (very hilly and rainy with lots of cars makes for many pavement breaches) Probably wouldn't work "as is" for gravel riding. On the bike path the batteries stay in place better. I can't tell if the brake light really operates properly but the bright mode is great after dark and the daytime mode does prolong battery life. The battery life is good. Auto shut-off works. It is highly water resistant, I have used it in heavy rain. If it works like this for a few years or more it's great...
