    Purchase for my 2025 Forester Sport, shipping was fast, installation was incredibly easy, works as advertised. Nice thing about 4D's Eliminator is you can hide it's presents by turning Stop/Start on before taking in for service, system will operate like factory.

    I've purchased 2 and they are great. I no longer had to keep remembering to shut of the worthless switch. I wanted one for a Buick Envision but they didn't make one. I bought another car.
