My kit arrived well before it's estimated delivery date, and was very well packaged. The installation went pretty well..I was not willing/prepared to cut the hinge off the sensor, so took my bike in to the shop for that last piece. They were able to attach as sent with a less-than 3mm gap, and it's all working great. Made my bike commute a joy with evening heavy panniers on an up-hill ride. My only wish..well 2 wishes. I would like to be able to go from a level 3 assist back down to 1, without clicking up to 5 first. And the battery doesn't turn off on the bike, so you have to remove the battery to keep it from drawing down while it waits for your next ride. Even with the minor challenges of adjusting the install, I'm very happy. I love my 20+ yr old bike, and the assist makes my evening commute a breeze.
