I was searching to install Xpel XR plus as the reviews on youtube were extremely good, so i did my search and i found Apex, to be honest the communication via WhatsApp was very easy compared to other companies, even the price was straight forward and it covers everything including the roof, Alex the manager was very welcoming and informative even he offered me a ride after that I handed over my car, the work was done on time and at the same day, when I received the car it was having few bubbles, but after three days everything was gone. As for the results and the final feedback about the product, I have a black Tesla Model S, you cannot imagine the heat that is coming from everywhere, I can tell you there is a substantial impact on the heat, even I felt that the A/C is more efficient after installing the Xpel.
And finally the product has a 10 years warranty, highly recommended.
