“So, I put in the MVC and the MFA, which is the volumetric meter and environmental meter. I closed with Taís and I tell you, I researched several companies, I went after everything... Man, they (Excelbr) have a sensational guarantee, service and a product that is also (sensational). I can't complain about anything. If I complain, I'm lying. They have the cell phone system too. A simple and practical system to use, all information comes in the email. The issue of monitoring is really cool, and it’s really simple, okay? That's what made me buy... In terms of assistance, it's really cool, they're ready to help with whatever you need. When it comes to payment, they help as much as they can. And from my side (products and service), it was the best there is.”
