It could not be very different from the vacuum version. Also, back when the electronic first came out there were electrical gremlins being caused by it. It seems they got those figured out. This is the only reason why I bought the vacuum version early on and then waited over a year to install it.
Vacuum version works great for 120 miles every day on my way to work.
