Garmin

I bought the edge 130 to upgrade from the edge 25. My primary objection to the 25 is it's poor battery life which seldom lasted more the five hours (in cold weather much less). I am very happy with the 130. I've used the device for several months and on one occasion used it at least 8 hours and it still had charge left. I also really like the small size. It takes little space on the stem. It links with the satellite much more quickly and more reliably than the 25.

I'm only downgrading my review to four stars because it doesn't have a convenient mapping feature. Since purchasing the 130 I wish it had more robust mapping.

I am, nonetheless, very happy with the device and for the price I am still getting significant value.

I won�t lie, there are false positives, but this is still a great tool for helping keep you safe. It�s most impressive moment, was insisting that there was a vehicle behind me, I heard nothing so didn�t believe, but checked before making a left turn. There was a Prius seemingly just back of my left shoulder in stealth mode. (I�ll give the driver credit, he was allowing me space to turn.) The false positives occur mainly in traffic, this device works great on open roads. The additional safety, far outweighs the false positives.

Extends the battery life of Garmin Edge on extended rides. Be sure and keep it turned off until Edge battery is near depletion. Unfortunately it only works with supplied Garmin Mount. (I have other mounts that I prefer but they will not work with the "mating process").

I use this for both my road and MTB rides. It has a lot of screens to customize for each type of ride. It offers a lot of flexibility.

The only think I would add is an easier way to select the bike being used at any point in time. It is necessary to access the app to select the default equipment for the activity. It should automatically select the default equipment for the specific activity.

It should also have a cadence sensor included in the bundle.

It is a good beginning.
