Bike Sentry Tail Light Alarm

i've been using this for a couple of months now, and it's been a solid addition to my bike. as someone who rides around dallas for errands and leisure, the visibility it provides is a big plus, especially in traffic. i like that it's easy to install—no fuss, just clip it on and go. the alarm is a nice touch; it's loud enough to make me feel more secure when i leave my bike unattended for a bit. i did have to figure out a hack to adjust the sensitivity by placing it in a certain spot to avoid false alarms, which helped. compared to other lights i've tried, this one holds up well, but the battery could last longer between charges. overall, it does what it promises without any fancy jargon, and it arrived on time, which was good. i'd recommend it with a note to keep an eye on the battery and maybe tweak the settings if needed.
- Pros: the light is very bright, making it easy to be seen from a distance, which i appreciate for safety. the alarm is loud and seems to deter unwanted attention, and it was simple to attach without any tools, just snapped right on. it feels sturdy and doesn't add much weight to my bike, almost light as a feather.
- Cons: most likely, the alarm might be too sensitive at times, going off when it's not needed, which could be annoying. the battery life isn't the best, needing frequent recharges, and in very hot texas weather, it gets a bit warm after long use.
