New input case for you: Loved this from the moment I put it on the bike. Took a little work, just a little, but switched it to my wife's bike and then back to mine. Some where in there we loaded it down too much and one of the slide in plastic brace ears broke and now it is unusable. Searching for a new way to haul groceries now...
Output:
Negative
