I visited Ban Hock Hin (BHH) for the first time today after my OBU displayed an error screen. I was very impressed by how organized the company is. After the swap was done, I was kindly greeted by Ms. Nana who went through what was done and also the things that may void the warranty. The entire team was fantastic .They were all professional, friendly, and extremely helpful.  A seamless experience from start to finish. Highly recommended!
