Not yet used, all parts and connectors are of good quality. Seems very easy to use. The size is perfect to always have with you on the bike. My kit only had 3 plugs not 6. The seller was great and fixed it quickly. One note: the instructions say there is rubber glue for the end caps. It is not included and no longer needed as the mushroom plugs are an upgraded type which the seller says seals better. Eliminates the work of transferring "goo" that can dry out or just get messy. If you ride any distance, get this kit and be ready!
