I have one and works great - have had it for three seasons with no issues. To be frank, not sure how much difference between the Optima and my other two batteries which are standard wet cell. I rewired everything the same year I bought the Optima to have one battery only start, one battery only trolling motor, and one battery all the accessories. This really helped my electronics and got rid of interference. The trolling motor battery seems also to last a lot longer now but not sure because it is an Optima. May be too much information, but I like them.
