I purchased four Xscorpion BTRP for use in an under hood, dual battery application. The product was ideal in terms of ease of use, number of connections it offers, and terminal size. However, within ~1 month of use oxidation began to show on the Xscorpion BTRP. I cleared this away and coated all terminals in dielectric grease (which I had on hand) in order to arrest the problem. I'd recommend these for internal/indoor applications. Unless you have an external/under hood application where you don't mind using dielectric grease.
