Switch works very well. In my opinion, the push-pull button is much more convenient than the engine brake toggle switch. Would give 5 stars if the quality was better. The manufacturers left a hem on the handle and the sticker on the handle was puffed up before I even opened it. There's nothing that slime and a piece of Emory's tissue can fix. Some people have mentioned issues with the rattling lever. Haven't heard a sound yet, but I put a hair tie on him right away, so don't expect to hear itβ¦
