After customer support finally resolved my issue, I'm updating my review. The light has really nice features, especially the LCD display showing remaining battery, and some quirks, which I'll later describe how to fix. Ultimately, it's the light I've always wanted someone to make. The Garmin-style mount is also fantastic and light weight. It also holds the light very securely and has a number of different sizes of straps. One person here commented that the light is heavy, but it's not at all. Nearly all the weight is in the battery, and it's sizeable, which is a good thing. Still, it comes in 70g lighter than my Moon commuting light and about the same as my similar Cygolight. I really like the beam pattern, bright in the front with just the right amount on the sides. I was afraid that with only one light, it would not have good sideways spread, but it does. Now the quirks. Bluetooth didn't work. so I sent the light back. The replacement had the same issue, so I contacted support and received a response that they'd get back to me. A few weeks later, they did, after apologizing for a delay due to the 4th of July (which apparently fell in October this year). The fix is to pull out the battery and put it back in. Initially that didn't work, but I did it when the app was searching for the light, and it worked. Inside the app, hit the add button, and you can create some really nice power modes. Another quirk is the remote pairing instructions didn't work. I suspected the battery was covered, as is common in a new product. I opened the remote, and that was it. I removed the plastic separator, and it paired. For the most part, the remote probably isn't useful, but for the ability to toggle the power up to maximum. If you hit a spot where you need a lot of light, you can punch it up to high and back down with a click. A scary quirk was when I was riding on a trail in the middle of nowhere, and the light completely shut off for a couple seconds, and then resumed working. That has only happened once in the 6+ hours I've used it, and it did come back on fast. Still, it's terrifying to be flying along in utter darkness. I suspect it's a software glitch as the battery fits very snugly. The unit is solidly built. I dropped it on concrete a day ago, and it didn't leave a mark on it. Even with the light cutout, I'd buy it again. I have had this happen on other lights, and it was worse. It has so many features, all of them useful.
