SEEMEE 300 Smart Tail Light

I'd say this is a 9 out of 10. The only reason I can't give this a 10 or a complete 5 stars is because, as far as the performance goes, the batteries just don't last as long as they advertised. It's decent, just not what's advertised in real-world usage. But other than that, from the quality of the product to the fact you can tell they paid attention to certain details, like for instance, I'm a short rider so normally my seat post is pretty low, like pretty much down to where the seat touches the frame of the bike, lol. I realized the light curved outward from the seat post, and I realized that small detail made it so I'd be able to still have my seat pretty low for my comfortability. Without this small detail, I'd have to adjust my seat post higher so that it doesn't interfere with the light or cause the light to fall off. This is a solid 9 out of 10 or a 4 stars out 5 👍🏽

If you are looking for a rear light .. just get this one! Brilliant light, excellent build quality and last ages. Highly recommended!

It works as described. Locking mechanism is a little scary but it’s nothing a single drop of superglue won’t fix. That and a long usb charging cable I got to charge it where it stands. I don’t remove my light to charge it. I charge on my bike. I’ve lost too many rear lights in my day due to bumps and never again. Hence the single drop of superglue that could easily be defeated with a single razor blade if I wanted to remove it for some silly reason. The light lives on my bike. Match made in heaven.
