Review on BlueSunshine Bicycle Motorbicycle Yellow Colorful Sports & Fitness by Shawn Tolbert

Cheap plastic. The build quality is not very good. I put one on a slightly dirty valve stem and it broke on the way. The other has plastic parts in the thread and is therefore unusable. Some of them are also very curved. This made it difficult to cut the thread near the spikes. The packaging was rubbish too. Even the Revains shipping envelope was better than what the seller put in the package. Generally very dissatisfied. BUT I WAS SURPRISED to see that it also includes 20 euro adapters, that was great.
