Delivered two very bright flashlights with storage pockets and handlebar brackets, a rear light for mounting on the seat post as well as a gimmick two valve lights. Only the latter batteries are included, total hits needed eight AAA cells.
The flashlights are very bright, I would, however, give me a hint wished that they need to be shortened when using AAA cells instead of 18650 batteries (see my video). The bracket stinks of plastic, which is acceptable for me considering the fact that (except during installation) no skin contact is made, and the wheel is indeed used outdoors. The holders can be adjusted well with quick plugs. They are (at least in urban driving) and stable.
The rear light is to be mounted a little fiddly, but does the job. The different light modes can I find rather disturbing, because you can not install just exhibit, but must first click through all modes.
The valve lights are a nice gimmick, but nothing more. When standing they do not light, and through the operation button cells are not exactly sustainable. They can not replace the side reflectors.
Overall I see the product but quite positive. For a review should also consider the price you wanted. The corresponding mE about the value of the flashlights. Everything else so there is to it, and the torches of course you can use independently from the wheel. Who uses his bike sporty, is probably a more significant, more expensive solution happier, but for occasional drivers in the city, the set is definitely worth a recommendation.
