Magicshine SEEMEE 300 Bike Taillight,300 Lumen Bike Tail Light,5 Night & Daytime Modes,Smart Brake Sensor IPX6 Waterproof USB-C Rechargeable Rear Bike Light for Night Riding

This is a solid light. USB-C, solid construction, battery life meter, easy to use, downward light... however, the light patterns themselves aren't as impressive as the Knog Blinder. In fact, this particular light does not have an aggressive FLASH setting — they are all more of a gentle/soft strobe. That said this is the light I use on my daily road bike. My partner has the Knog, which uses legacy USB-A for charging.

The SEEMEE 300 is a capable and bright light with multiple functions and outstanding battery life. I have other high-quality lights (NiteRider) and this one rates as well as those, with the caveat being that this light is quite bulky, but with the kind of battery life it packs, I can't complain. It's not like I'm a professional racer who's shaving off grams of weight from my bike for competitiveness. So, a little bigger light isn't too big of a deal, it's not distracting and it doesn't really compromise aerodynamics (again, see sentence about NOT being a pro racer). The price of the light is competitive with upper-end brands, and I'm a firm believer of "You get what you pay for...". I'm quite happy with this light, and again the battery life is proving to be spectacular! I've owned it for over a week and after its initial charging, and 90 to 130 minute bike rides 6 days a week, it's not showing any need of recharging. Though after today's ride, I suppose I will just because I have to charge my headlight and head unit anyhow.Color me impressed. With multiple pattern flashes and settings, this tail light is suited for 99% of the riders out there who care about being seen by others and by drivers. I would purchase this light again if I needed to, very much worth the cost! Five stars.

This light has awesome visibility! Mounts similar to other rear flashing lights. Still learning about the different choices. You don't really know how good your rear flasher is until you see one of these go past you. Very quick release from mounting by a quarter turn. The seat mount bracket doesn't fit my bike seat rails but that could be my seat design.

Fantastic light - I looked at a lot of lights and finally decided on this one. It is fantastic and has a lot of features. I am very happy with the purchase. I definitely know people behind me in a car or other can see me. The brake light feature is cool in bunch rides. I like that at dusk it puts a light on the ground too.For sure a great purchase

So, the light features are great, I really liked it. The smart sense braking seemed to work well, and the 10(?!) different patterns and modes were neat. However on my second ride with it, (note: on city streets) the seat rail mount that came with the light failed at some point, and the mount and light were both gone when I arrived at my destination an hour (11 miles) later.I made sure I clipped it on correctly over both rails, but apparently the bike coming off of a curb when leaving a green way or something was too much jostling force for the mount to stay in place. Is that surprising? Yes. The install was straightforward, but that thing was hard to get over both rails, and felt firmly clipped in place. I now wish that the mount came with something to lock it in place, rather than just relying on the clips being tight, because clearly it can't adequately hold on to the rails with the leverage of the weight of the light on it. So here we are. I paid good money for the product, used it as intended, and it's gone.Would be a great product for the price, but the crap mount holds it back.

The media could not be loaded. The instructions lack clarification on what mode is what. Wish it didn't have the small led that presses down, or a mode with out it. That way I could use it sideways. Really wish it was as simple as the front . Overall it's bright, happy with purchasing power. Execution is just not great

Very bright and long lasting battery

Easy to charge, easy to connect, nice and bright.
