Turning on my levelling system has given me concerns ever since buying the 2018 Precept 31UL in 2020. I'd have to push hard and hold the on/off button for several seconds before I'd get the unit to turn on or off. Called Lipert and they said the touch pad had to be the issue. $650+/- plus tax. Did some research and found the below unit from Power Gear for $373 plus tax. Got it in 2 days, installed in 5 minutes, comes on and off just like flipping a switch. Stored the old one as a backup just in case.
