I figured I would share some of the updates with my Garmin Vector 3 pedals that I own. I for starters have had mine since the beginning of December and never really had any issues with them - I however have read all the issues other users were having and was always worried about the accuracy or if they were going to give me grief.
Garmin IMO released a product that was not 100% ready for in field usage but has since released software update 3.50 that fixed a lot of software issues and also solved legacy head unit issues. They have also released battery doors after discovering that a lot of the software/battery and other issues were being derived from the door issue.
I do own a lot of Garmin products, so yes I am well vested in the company but not supported by them - I think that they have handled this issue very well (my current employment deals heavily with on-site manufacturing) and although the situation is negative I always received great customer service and decently quick responses from Garmin.
It is easy to talk about something when you are upset than when you are happy and Garmin being one of the largest manufactures in recreational sports more than likely has the most units out to be criticized.
Anyways - I wanted to share some photos of the new doors that I received yesterday, so far they L/R balance is perfect and power seems to be spot on. I have not gotten any outdoor or long rides on them yet but everything about the redesigned door is better (including how it locks/screws onto the pedal body).
