I installed the Fell Marine Mob+ myself on my 23 foot day cruiser a year ago and it works very well.
The only problem I've had is false positive cut-offs when I'm on the dock untying or when I prepare to dock and I use the arm with the wireless FOB on in the rear compartments of the boat.
I could probably fix it by angling the antennae so that it was upright instead of pointing out horizontally behind the base unit, but TBH it's such a infrequent issue and only happens at no/low speed anyway that I haven't bothered.
On the plus side at least I know that it does cut the engine and probably would in a real situation as well.
