They didn't pressure me to buy anything I didn't need, which I really appreciated. I've been to other places that pressured me to buy stuff and it always made me very uneasy. They always have an immediate answer for me when I call with a question. They would never try to get me to make an appointment unless I really needed one. One thing I love about them, is that they're always willing to ask for other qualified professionals' advice when they don't have an answer for my question. I never have to worry about them giving me a wrong answer just because they weren't willing to ask for help.
