Review on CIPA 03001 Gray Wireless RV Leveler, Compact Size - 6.2 x 9.4 x 2.4 inches by Micheal Esquivel

It's a waste of money. I received it, set it up and immediately checked its accuracy with a high quality 9 inch torpedo level. The level of the torpedo showed that my wooden floor was perfectly level. CIPA 03001 specifies that the floor is more than 1/2 inch out of level for the entire length of the unit. That would be over a foot the length of my RV. Useless. I immediately repackaged it for a return.
