Go to Garmin Vector 3 forum and look at the shit show... that is a good place to start lol
I'm not going to say there aren't problems (because I'd be wrong) but a company utilizing a support forum always magnifies problems. On one hand its great to get a fix by just looking at the forum, on another you air out alot of dirty laundry which may seem to be the norm but is not.
Companies that are tight lipped and suppress customer support by only allowing email do a much better job of hiding problems.
That being said, my next PM I'm leaning towards Favero, because it seems to be great quality and its made in the Veneto.
