I came to Adafruit after purchasing some samples of their batteries, and being content with the quality, I wanted to purchase an in bulk order quality of around 150-200 pieces to begin. my requirements were simple, I needed reliable and ongoing large quantity orders of these. I asked if they were able to accommodate these quantities, because I would never order them if they can't. I also asked for pricing per piece of these large quantity orders. I submitted an inquiry. "Kelly", who was very rude, told me that no one at adafruit can answer any of my questions and basically told me to get lost. This is no way to run a business, and I am honestly disgusted with the customer service. I would not recommend this company to anyone and will continue to try to keep people away from them. Most other reviews seem to coincide with my experience.
