So easy, Black Jack

23 May 2024

Bought because winding the jockey wheel up was becoming too difficult. The Black Jack is so easy to operate, easy to level the van and very sturdy. So far so good, would recommend to anyone.

This is a very good option to the standard jockey wheel and no more screwing the clamp closed or winding like crazy to raise/lower jockey wheel. Love the night light and the lift up foot. Be even better when I connect to batteries in the van

Great product just getting started

Great product and excellent Service

3 March 2024

I love this electric Jack it saves my aching bones from the hassle of the jockey wheel. It was easy to fit and I used the supplied wiring harness. For me the standard leg is best to cope with all site conditions. The service by this supplier is excellent and I will use them for future purposes.
