I hope the rear light will provide good service, but it was frustrating there were zero instructions with the package. No QR code, nothing written on the package itself, no paper insert.The light has smart features like auto on/off and deceleration warning, but no indication of how to engage these. I had to return to the amazon website and read all the way through to find these bare-bones instructions."Auto ON/OFF - Press and Hold the Control Button until the Light is On and You are Good to Go"then further down the page..."After charging the battery, simply press and hold the control button for 1.5 seconds to turn it on. You are good to go for weeks.."There should have been some clue about how to engage this feature included with the product itself.

All of the features work, including the brakelight feather. BUT, the light itself is VERY dim. I charged it to 100 percent and still the flashing/strobing modes are barely noticeable in indirect sunlight, let alone direct. It could work okay as a light for the dark, but for a light during the day, it's far too weak.

Brake light is easy to install and so nice that you don't have to remember to turn it off. There were no printed instructions in the package but it's easy to figure out. It's bright and continues to flash until bike was stopped for just about 2 minutes.

This tail light is nice and bright but I think it is way too sensitive. The very slightest change in speed up or down and the brake-light effect kicks in. Thus making following traffic confused as to what the bike in front is doing. If the sensitivity could be altered this light would get 5 stars.

It is not a bright daylight tail light but it’s auto on/off function is great . The battery does not need recharging very often , in fact after the first charging I’ve yet to recharge . I bike about an hour and 1/4 per trip and while I’ve been busy with other pursuits so I’m not riding as much as I often do , I find this feature is really great.

It is very simple to fit and the brightness is good but it's not very strong got the feeling it would break very easily.

It has different light modes, and theyre all bright. And then it gets brighter when it senses you slow down, acting as a brake light. Battery life seems to be very good. Some people say they are having trouble with the latch, but i have mine on my backpack and it works fine, no issues for me there but I could see where it could be more secure. Would recommend

I read a few reviews about the light falling off. It is correct there are no mounting instructions, so I looked over the attachment carefully, and saw that there are really two hooks from the same latch mechanism. Once you've looped it around the seat post look closely and you'll now see another hook (back side of the S hook protruding). Hook the last loop with that and it will now be secured with two hooks. I'm hoping by doing that it will be much more secure.

I must admit, I was uncertain about this purchase. But the rear light does exactly what's promised. It turn on when it senses motion, and the lights get brighter when I slow down. Easy to attach ... easy to charge (though ( haven't needed to do so). This is a gizmo you can buy with confidence.

I'd say about 80% of the time I forget to turn on my rear tail light when going on a bike ride. I often forget to turn it off too until I'm home. This product solves both of those issues.Came in a nice package and looks to be built well. I tested out the stop-start lights by hand and it does appear to work well with little motion as described.I'm leaving it 4 stars for now for two reasons.1. It didn't come with instructions. Granted it is pretty simple to operate but a little mini page or two guide would be beneficial for people like me that may accidentally break a product while unattaching it from the seat connector to the clip. That didn't happen, the plastic is very sturdy.2. I haven't used it out on the road yet. If my friends say it works well behind me definitely will come back and give it 5 stars.Rechargeable for 90 hours is a lot of seat time too and no battery needed! Another nice feature.
