In full disclosure I was shocked at first sight at the cost of an Spod unit, having a fairly strong background in both electrical, electronics and machinery. I was taken back, but my curiosity got the best of me, so I took a closer look at the system, design and engineering, safety features and variable functionality. Spoke at length on several occasions to John and later on some of their support staff. Eventually I went to see their facility. My interest went beyond the off road usage. I sell build and design custom vocational trucks from well drilling and servicing trucks to HD service trucks for municipal applications for water and sewer systems.
One year later after testing a source SE , I approached them about be coming a dealer, its been about three years now. The key with any product isnt just the upfront cost but the durability and total cost of ownership. When something does go wrong is there someone to call? And do they stand behind there product?
I cant say anything about switchpros good or otherwise, but I can attest to the high standards that the SPOdS are built to, and the family that stands behind them
Good Luck
