The one shot version was no good for me as the signal disappeared behind buildings.
I have several properties that require 100m to reach a property whilst parked on a beach and various places out of sight and a further 100metres of lay flat hose to reach around the properties. This version works out of sight and obscured from buildings for definite where the other one didn't. Means I don't have to leave the pump running until I'm set up and can control the flow using the app on my phone or from the fob which I keep in a pocket. Easy enough to set up the settings to your own preference. Works well but have to charge fob within a week as it runs down the more it's used.
Stops within a couple seconds and starts the same, ideal the further away from van where obscured buildings would normal be out of range for signal.
