I too have a squeak/rattle from the drivers door that I did not notice when it was colder out. Very annoying and I will see if its the same spot your problem was at, thanks!
Glad you like it, from what I can tell (from the install instructions) the WeatherTech unit is the same as Lomax and they look to extend the warranty from 3 years to lifetime. Think I will be getting it very soon.
