Bicycle Tail Rear Smart Brake Light with Vibration and LED Lighting

I bought this hoping it would make my rides safer, and from what I feel, it does quite a good job at that. The automatic brake light is a smart feature that works as promised, alerting cars behind me when I'm slowing down. I've used it for a couple of weeks now, mostly on city streets during evening commutes, and it's held up well in light rain. However, the vibration feature pings me for every little jolt, like hitting a small pothole, which is more distracting than helpful. The multiple light settings are nice, but I find myself sticking to one or two because switching between them isn't intuitive. Overall, it adds confidence, but it's not perfect—I'd recommend it with some reservations for those who want simplicity.
- Pros: It automatically turns on a bright light when I slow down, which is great for safety without me having to do anything. The different light patterns are useful for various riding conditions, and it's built to handle wet weather well. Installation was quick and easy, fitting my bike without any hassle.
- Cons: To be fair, the vibration alert can be a bit sensitive and goes off for minor bumps, which is annoying. The light modes might be too many for some, making it confusing to pick the right one quickly. It feels a bit bulky on the bike, and I wish it were more discreet.
