I bought this product for just under 50€. The grips are 120mm long, while the throttle grip has the bone integrated, where the throttle cables attach (so you remove the existing one). The cables are relatively close together but it's not a problem. The big negative for me is that, as shown in the photo, the unit and the plugs are completely loose, so if you want to use them for a moped or scooter where they will be hidden inside the handlebar plastics, it's okay... but if you want to use them for a motorcycle like me, you will have to find some kind of solution with a small electrical junction box or something to waterproof and protect them from water and dirt. Also, neither a fuse nor a fuse holder is included (also essential to protect the circuit from potential short circuits and fires), so if someone wants to install them themselves, they will have to purchase those as well. I don't know how much they will withstand, but I hope they hold up. For their price, I consider them okay and worth it for the winter.
