Everyone in the Southampton location was helpful. Had no issues with the unit. I just don’t like that the price increased $50 after a few months. That’s a big increase for such a small unit

We're delighted to hear that everyone at the Southampton location was helpful. We understand your concern about the price increase and appreciate your feedback, Cindy.
