I recomend the Tekin RS or RS Pro. The RS has a 5t motor limit, while the Pro doesn't have a limit. I have one of each and use both weekly. They work extremely well with sensored and unsensored motors, and what is really great, if your running a sensored 13.5, and either a sensor goes bad, or the wire comes out, it will switch to sensorless without skipping a beat. The Hotwire software is top notch as well. It will give you the ability to lock out the reverse, or put a delay in it if still desired.

As much as I have tried to kill them, they keep working. I even accidently reversed the battery wires once, and it all kept working just fine. Did that to the orange brand, and it smoked immeidiately.
