Amazon had 17 of this item in stock when I placed the order but took 5 full business days to pack and ship. I purchased 17 of these and paid for 1 day shipping but when they finally packed them and sent Fed Ex the delivery date in tracking was 3 days and arrived in 2. All along customer service was clueless on the order and kept giving me different excuses or guesses. So when they finally arrived late and I had already been forced to find the units locally so I had them sent back to Amazon. For the return I received 17 separate emails that they had receive them and then 17 separate emails crediting my charge card for each one. All in all the worst experience I have had with Amazon.
