This place is amazing!!! I wasn't sure if I wanted to replace something and Earl spent a LONG time explaining how to monitor it, what to do when it did run low, and how to fix it. He made sure I felt comfortable handling it and I never felt rushed. I really appreciated the honestly (could have just told me to replace now) and time he spent teaching me till I was comfortable. This was not the first time I have had great customer service here. They are consistently awesome. They don't recommend every little thing, so when they do say they recommend something, I believe them.
