Tool was exactly how described and packaging was nice. It did take a few days to ship so unfortunately I didn’t receive it in time for the trip I ordered it for which is the reason for 3 stars but I received it the week after and it’s coming in handy.
size is big enough and clear simple layout. moved from garmin 850. I am very satisfied with wahoo!
Sierra is no joke, this is our 4th bike in the last 3 months and the process has been so easy, they are fair with pricing and never make it feel transactional! I won't be buying anywhere else!
