The motor works really well. It's much quieter and the head spins faster than the Terrova. Also holds spot lock much better. The only thing I don't like is it's slower at full speed than the 112 Terrova I had. I can do 2.6 mph on the Motorguide wide open, the Terrova would go 3.2mph. Other than that so far it's been doing well.
One thing I learned when I first switched over, Motorguide's customer service is totally different than Minn Kota. If you get a new motor from Minn Kota and out of the box it doesn't work or it's damaged, they send you a complete motor. Motorguide wants you to have the damaged motor repaired.
