Commuter X4 Wearable Rear Light

This is just great for backpack. The red is bright. I can select a few options from blinking to steady light. On full charge, it last a long time. The big round light in the middle makes you look like iron man. All in all great purchase!

Great when I run or ride my bike early in the morning. I always have a backup because they do burn out after several months, but it’s not a problem for me because cost is so reasonable.

I've had the light the last few days, and haven't gotten hit by a car yet! Don't know if I can give the light all the credit, but hey. One design suggestions I think could be improved is the center circular light could be enclosed in rubber around the perimeter. The plastic feels like it may break with enough impact. Another is the elastic band needs an adjustment strap so you can adjust it's length like the other two straps. I'm planning on retrofitting it so it does but I find the light constantly sliding to the side of my backpack and not staying centered because it doesn't fully tighten around it, only at the top.

When the unit is fully charged it is super bright. When the charge starts to go down it shuts off randomly after a short time. I ride 7 miles to work in the dark and sometimes with a low charge it won't even stay on. it helps to make me visible on my motorcycle. I bought two in order to make sure I always have one fully charged.

Works, and is half the price of the "name brand" that even uses the same model number.

Nothing

Excellent bike lights

I have it attached to my backpack for when I riding my bike. The main light is very bright that it can even be use during the day.
