If you would spend more money providing the support your customers need versus setting up multiple stands at an event to try and attract new & repeating business you would probably have happier customers and repeat business. Although, you eventually helped me with my part replacement. It came with great effort on my part. So much I had to put calendar entries and reminders in my phone to call every day for almost 2 weeks until your only customer service person finally put my part in the mail. I spoke to other people who promised me my part was in the mail. Lies! I finally spoke to the customer service person who's name I was given at least a couple of times and after a few calls with this person I actually received my part. This is not the way to treat customers you want to buy a second and possibly third pair of expensive sunglasses.
