Summary: Beware the refurbished ones, they don't come with the free year of service. Garmin wants $49 on top for that.* Update: I contacted Garmin by email and they added the 1 year subscription for free. It did take 3 days for them to get back to me.
Summary: I've been using an Insignia LittleBuddy for the past year, so my perspective might be different than others on here. I had been VERY happy with the LittleBuddy, but both my main and backup units broke (My only complaint about them... poorly built, and prone to frequent breakage), and when I tried exchanging them aga.in, Best Buy told me that they had recalled all units, and no store had any stock.
Summary: I had a DogTracs unit for a year and overall I was satisfied with it, though I needed to charge it every day. In comparison the Garmin is smaller and sleeker, though it resides in a little zippered bag on the dog's harness, which adds to the bulk. Set up was easy once I used IE as opposed to Firefox which just couldn't seem to handle the Garmin download.
Summary: Quando si trova dentro edifici non riesco a sapere dove si trova. Neanche l'ultimo punto prima di entrare. Provato con mia figlia, messo in cartella, non mi sapeva dire neppure il paese di dove è la scuola. All'aria aperta è perfetto.
