  • Solar for the win
Style: Edge 840 Solar
I’m really glad I purchased this. It exceeds all my expectations. After reading the reviews and watching videos, I nearly passed on the upgraded model with solar. I splurged as I’m a sucker for all things solar. I’m actually blown away that I’m getting 20% battery return in high sun environments. I had over 17.1% (20 min) gain on an almost 2 hour ride with sun and lots of shade from trees. The battery lasts for a LONG time. I would like to be able to do more in the app to customize screens, etc. The touch screen works really well and there are buttons for all actions if needed because of gloves, etc. I had a bit of an issue with loading the USA maps on it at first and had to finagle things a bit. Typical Garmin issues. Overall, a great product and was the sweet spot for me with all the options available. What a great buy. I’m very happy. ... show more

  • Oh Garmin
Style: Edge 840
How I love Garmin. Like Apple once you get one you will eventually want them all. Like a demanding wife who wants more jewelry Garmin has me buying the whole ecosystem. Don’t buy this unless you plan to buy a heart rate strap, a radar light, power pedals, a watch, an emergency radio, and a trainer. This thing works great most of the time and honestly can’t believe I biked for 2 years without it. Garmin knows how to make the battery last forever and it’s been easy to use. ... show more

  • Faulty product
Style: Edge 840
It worked great, until it didn't. I tried getting a replacement and was offered "technical support." Not only was that a joke, but they took weeks to respond and offer me "support" that is already listed on the Amazon page. I am writing this review after months of not hearing back and not getting ANY response. ... show more
