also having used/installed a oem-1 would recommend it.

I think there's a typo or two in that sentence, I believe you're asking me a question, would I recommend the OEM-1?

I think it's very car-specific as to whether it works well for a particular vehicle. For the vehicle I installed it in, it was fantastic and made the installation very simple. Don't know how your car will come out. Photos of and comments about the OEM-1 install I did are here.
