I can't help but wonder how many of the warranty claims for backends were just for a dirty backend. Don't get me wrong, I'm sure there are defective backends out there, but I think the number may be much smaller than it seems. Between that and the issues that were caused by the charger, I wonder how many warranty claims were for an actual defective Grasshopper. It sounds weird but finding that fix has improved my confidence in the hopper's reliability. I have to give a lot of credit to @GreenHopper and u/Reeces_Pieces from Reddit. I wonder why Reeces deleted his post? I'm just glad @GreenHopper was nice enough to post it here. By the time I saw it here the original post was already gone.
