The Paradigm remote works fine if you put the pump on vibrate. It's kind of like doing a bolus in the dark with the pump. It does wear down the batteries a little faster, but that's manageable.
I have only used it a few times because it is another thing to deal with. The remote has the bolus and escape button and function is the same as the two buttons on the pump.
It is pretty basic and does make it very convenient if you want to stash the pump. I use it when I need to hide the pump or put it in a waterproof case for kayaking.
