Robotshop saved the day!
I'd give six stars if I could... I had purchased a product from another vendor one week before Christmas with UPS next day shipping, but they shipped it USPS and it was going to arrive one week after Christmas. I contacted Robotshop and they were able to overnight me the same product to save the day! Their support team responded very quickly to my questions, and made sure things went smooth along the way. I'm now purchasing all of my hobby electronics through them. It's great to find a company with this level of support!
