Bought the lock’n’level almost on spec. Firstly, terrific service from the company as I needed next day delivery as going away. It arrived promptly. Secondly, using the product was so simple particularly as I am required to use an Alco wheel lock by my insurance company. Trying to get a correct level whilst trying to get the wheel in the right position is impossible. Lock’n’Level makes it so easy. 2 or 3 minutes to inflate it to the right height and even after two weeks it still held the correct pressure to keep the caravan level. Other campers saw the product and were impressed. I was able to give out some leaflets which came with the product. To summarise: its quick, simple and reliable. The Caravan Club should support it.
