While the reps I spoke to could not have been more polite and honestly gave me the impression they were knowledgeable about their products, I spent literally hours over days on hold and with reps that never resolved my problem. Promises of follow-ups were never kept and I finally ordered the missing part from my order elsewhere at my added expense to just get away from this order. It's a shame - they have good prices and a lot of good products, but I can't deal with this lack of service.
