ToddYYC would know better than most considering how long he’s been a grobo user, multiple devices, the replacement parts he’s installed and troubleshooting involved. He was really helpful to me and for that I thank him.
I don’t think that it’s necessary to contact BBB. Grobo has quality assurances in place, but stuff happens. While I understand your frustration It’s clear that many more people have devices without issues than w/ issues much like any electronic device. If you had an LCD or board failure with your laptop in the first year any manufacturer would likely send you a replacement part and sometimes a certified tech to do the work. Grobo is similar.
The folks at grobo are really decent people willing to bend over to help users even difficult users like I was. It sucks your device is troubled and I doubt anything I could type would ease that anger/frustration, but I do empathize with your situation and hope you find quick resolution. Get your ticket in the que and I’m sure Stephen and company address it ASAP
If all else fails, cut your losses and follow the recommendations of some of the tent growers here on AG.
