I just wanted to mention MC's outstanding customer service. I've had a couple orders have some issues due to the extremely cold weather. MC was very quick to take care of me even though it really wasn't their fault. I've probably placed close to 20 orders with them so far, and have also ordered from at least 5 other sources. MC is top of the list for communication, shipping speed, and especially customer service. I also appreciate their transparency with their testing. I hope they stick around for a long time.
