Installation guys did a fantastic job. No complaints there. However, we were quoted on the latest release model, but they installed the previous generation (older model) and didn't tell us. I discovered this by accident, but I'm betting they didn't think I'd notice. I sent three emails to three different people asking why this happened. No response. A week later I got the invoice for remaining payment. They still had the new more expensive model listed on the bill. So I called them and only then did they say that there was no stock of the new model. They admitted they should have discussed installing the older model. And finally they gave me a couple of hundred dollars off. I'm certain that if I didn't call them, they certainly wouldn't have discounted the bill. Be wary and always check what you're agreeing to get installed with this company.
