Regulator Fix product review
 

On my 2003 was out doing a little after dinner drive.
Mrs. Aviator decided she wanted a little country air.
Not a problem noted till we drove near the cow feed lot.

"Hey Sweetie, lemme show you how this brilliant cabin air filter system works!"
Ahhhhhh, the button doesn't do anything.... window is stuck down.
Great, there goes the nice ride in the country in my new X5.

I had purchased 2 sets of Regulator Fix rail sliders from the guy.
Pulled them out and installed them. Such a great improvement.
Greased lightning going up and down. I also replaced the black
Window hole plastic pair. Naturally, they had lost 3 of the 4 tangs.
New ones flexible and dropped right in.

Anyway, I m a big fan of "Regulator Fix" guy. It's a good product, well designed.
And I feel it's a One-and-done job.

Both left and right front sets for under 15 dollars delivered.
