I got a Bolt. I was livid at Garmin, and after 10 years of bending over and taking it (Edge 205/305/705 and 1000). One of my mates lives in KC and I exchanged it with him for some beer ...he even went to the front desk of the Garmin offices to exchange it and it still cost $200. I'd played with a roadie mate's ELEMNT in camp one night and was sold on a Wahoo even before my E1K died.

These days most of my riding is JRA or planned or scouted by organizers...so the need to spontaneously reroute out of phone-tower range is low. Which is the one caveat ATM with any Wahoo computer being used for touring here in the USA--on-the-fly routing is dependent on having cellphone towers....and cell tower coverage is iffy, particularly here in the Great Plains.

The biggest differences are: no touch-screen, no color screen, and no unpaired routing in remote areas. Which if you can live without those things--it is a great unit. Most all the data-fields I can imagine are on both. Setting aside the obvious--the Edge1000 was huge (honestly too big with the gigantic bezels), the Bolt isn't. Battery life on the Bolt is way better without needing to turn any features off. Features like text notifications (full text not just a snippet) work (Garmin they were always wonky). The Wahoos don't have a "sleep" mode like the E1K does--so it is full boot-up/power-off which takes about as long for the equivalent as E1K.

Both Bolt and ELEMNT run the same firmware--only difference is screen size, bolt has up to 9 data fields whereas ELEMNT does 11.

The DCRainmaker reviews of the Wahoo Bolt gives good normal-use review of what playing with it a Wahoo OS unit is like. The ELEMNT review is very old, and there have been LOTS of changes since the original ELEMNT review was u-hence why I say look at the Bolt review. Wahoo actively maintaines their units, and generally updating is not an anxiety-causing affair unlike Garmin.
