Owner from garmin fenix 3 to epix, tactix and blah blah blah. I've never had an edge device because I see no real purpose other than the big screen. Instead I see a lot of problems with edge devices here. Is there anyone here who can objectively tell me whats the real purpose of an edge device is? With the problems I read here I am hesitant to buy an edge. Don't tell me about the battery because even with the tactix I have done over 500km on my road bike and at the end I had enough battery left. Whats the true pros and cons of the edge versus a watch? are there any functions on the edge that are not on the watch? Thank you.
