Hear from a Customer

Mario Blais, Director of Maintenance at Phoenix Heli-Flight

"It's been four years since this battery was installed and it's still performing as if it was new. At this point, I am so impressed with this system that the company has decided to upgrade the whole fleet with the TrueBlue Technology. Although I personally have nothing to gain from providing my experience to other operators, I never miss a chance to express my satisfaction with True Blue Technology and with EuroTec Vertical Flight Solutions."
