I was very pleased to receive my Swytch kit, but think a 6 month wait is a bit on the long side. Installation was relatively simple, and initially the kit worked well. After about 6 months I started to notice that the power drops out intermittently, which is extremely annoying. Also the battery which is the biggest available does not last more than 25km before needing to be re-charged. I convinced my wife to buy one as well, and had the same problem, the power cuts in and out, and of course you notice it most when it is needed the most! For my kit, I received support by email, which was prompt and friendly, but has only improved the problem slightly, not cured.
