Robert V. ★★★★★

Wired this between my starter and house bank and it switched over instantly when the main battery dropped. The 26" red cable was long enough to reach my aux fuse block without extending anything. Solid little unit for the price.

Claire ★★★★★

The 14" red and black cables included were the perfect length for my dual battery setup, no cutting needed. The smart isolator kicked in exactly when it should and my fridge has stayed powered all weekend. Solid little unit with real 6 and 4 gauge wire, not the thin stuff.

Zoe H. ★★★★★

Wired this between my starter and house bank and it switched over the moment the main battery dropped below charge — no manual toggling on cold mornings anymore. The lug connectors fit my existing .3125" terminals without any drilling, which saved me a trip to the hardware store.
