The pre-cut tint kit I purchased was great and all windows fit perfect didnt have to trim or make any changes to them, which made the installation process so much easier that had I needed to trim or had purchased the tint in a roll and had to cut to size my self. I also purchased a few tools to assist with the installation and the tools were right on the mark and really helped me out. Had one minor issue which was the fault of USPS, but RVinyl was amazing and took care of things for quickly so that all issues were resolved and taken care of. Very happy. If you are in the market to tint your windows and considering a pre-cut kit or anything that the website has to offer I would highly recommend getting it from RVinyl as they will take care of you and it is really hard to find a company that cares about their clients and RVinyl certainly cares!
