Pros: easy to use, cleans well, leaves surfaces shiny
Cons: if your car is really dirty, you still have to rinse it with water before using Eco Touch
The spray is really simple to use (spray, wipe, and polish). It saves time because instead of going through all the prep work, washing your car, and then drying it, you get all the steps combined. It left the windows in particular looking great (no streaks at all)! It's a good deal to spend only $15 (discount at the Green Festival - and that included both the spray and the microfiber towels) for a bottle that lasts a long time.
The only catch is that you can't use it on heavily soiled vehicles (needless to say, I had to take my car to the normal car wash after I went skiing).
