Delivery was a bit "rough" as the parcel obviously got stuck in EU-customs and UPS' communication regarding destiny and potential delivery was catastrophic. Never more UPS!!!! Installation of the Swytch set was easy: All the parts were as ordered and fit perfectly. Only the protection tape mentioned in the instruction manual was missing. The instruction manual itself is very good. I only missed the part regarding installation and connection of the display. The installed set works very well. You can feel the extra push when riding the bike. The only thing I don't like is the visible cabling "salad" around the bike frame, though I know that it is inevitable with this kind of product. Swytch's customer service (attending communication), as far as experienced so far, is very good. Wouldn't have expected that from a startup. Product price seems reasonable to me. In summary I have no regrets having bought the Swytch product. Far from it! All the best for your business idea and company!
