Review: Great light! Great price!! - I've been a bike commuter for the last eight years and that means riding rain or shine, day or night. As a result, I bought a lot of bicycle tail lights. This is one of, if not THE best tail lights I’ve ever owned. (I know some reviews have stated that the tail light is not bright enough during daytime use. Those reviewers need to look carefully at the instructions. The tail light brightness is controlled by a long press in the continuous mode.) It also seems to have some ability to sense ambient lighting conditions, and to modify the level of brightness, for example, when it gets dark decreasing from the maximum brightness level. I don’t think you would want to run this at the brightest setting in the dark on a group ride as you would blind riders behind you. At its brightest light is easily over 100 lm which is plenty bright. I just got it so I can’t say that I have evaluated if the run times are has advertised. That not withstanding, I would like to comment on the thoughtfulness of the design and the excellence of execution. The overall quality of this tail light is jewel-like. This appears to be a completely waterproof tail light with an IPX6 rating. It has very fast charging via USB-C, the three most useful modes, flash, strobe, and continuous, auto on- and auto-off, and an excellent and highly sensitive brake light I think that the included mounting hardware is extremely well done. I wish that more mounting options were available. If you run an under seat bag and have limited access to the seat post, it will be a challenge to mount this light. However, I was running an undeseat bag, and I like this light so much that I stuck my tools in my handlebar bag and I am running this with the saddle rail attachment. I feel very comfortable running this attached to my saddle rails, even though they are carbon fiber. The saddle rail clamp includes plastic liners which allow for clamp to be securely attached to the carbon rails without damaging them. In summary, I think this is a fantastic tail light. It would be fantastic at four times the price but at this price is it is a 100% no brainer! the best option for my money on the market.
Review: Quality product, well built with several mount options. - Had a few different tail lights on my mountain bike over the years, gotta say this is my favorite. Most are plastic and don’t mount great, this one is metal, solid mounting option (including under the seat instead of an elastic strap, and that bracket is awesome. Super neat install, looks sweet mounted in that space since I have a dripper post, and works great. Having the brake light function is pretty cool on descents on the trails at nights too. I highly recommend this light.
