      Clearly the third batch is NOT shipping out at the end of November. Do you have a new shipping date?

      Now, don't take me wrong. I'm not angry, just miffed and waiting patiently. The gifts will probably take the sting off...a bit... But you're going to have to do better because your stellar rep's being tarnished by this all the same.

      So the first, second and third batches have shipped but there are those of us who still haven't gotten our units. What is the present timetable for filling the outstanding orders?

      It appears that only the first batch, part of the second batch, but none of the rest of the second batch or third batch ever got their units. Just got an email telling everyone that they're cancelling the order and refunding.Thanks for the refund, Seeedstudio. At least it's the right thing...after months of delays.

      linusti- Yeah, I got the email. Like you I've b!tched here multiple times. Something smells fishy - maybe they should change their name to SeedyStudio. I already placed an order with adafruit - an extra $6.05 total for two boards isn't horrible if I do actually get delivery.

      Is there any way to see when ones order are expected to ship? You talk about first, second and third batch, but i have no way to relate this to my order, and know which batch my order is in. I placed my order on the 13h of september. Am I in the third batch then?

      I ordered 10 on 9/6 and 20 more on 9/9. My first ten arrived about a month ago (first batch?), the second group has not arrived or shipped (third batch?)

      I just received a shipping notice for my 3212's. As the page has partially updated to mention the 32s instead of the 3212, could you explain more on what is being shipped?

      Sorry for the confusion. We want to reassure you that ESP32S is the exact same as ESP3212. Name changed due to official production requirement. Please enjoy the product soon. Happy hacking :)

      So you mean that the footprint of the ESP32S is the same as the 3212? Earlier information indicates the 32S is different. This would change the boards that are being designed for these modules. I would also want to ask, the breadboard adapter "free gift", is is slim enough to use it with only one breadboard, or will I have to straddle it over two of them?

      I placed my order on the 6th of September 2016 but today on the 28th of October my order is still only confirmed and not shipped, even though according to your description it should have been shipped either around the 23rd of September or around the 10th of October depending on the time of the day that I placed the order. I'd like to get a new estimate on when my order will be shipped.

      Hi Erik, Please accept our sincerest apology. The shipment was delayed due to production issues. We've been working hard to restore production and prepare shipments. Lastest update of shipment date are as below:The 1st batch had been shipped on 28, October.The 2nd batch will be in limited quantity. Hence, part of the orders will be shipped within the first week of November. Rest of the orders are expecting to ship with the 3rd batch at the end of November. To express our apology, please kindly accept our gift, which will be in equal amount of your order quantity. Gifts will be shipped along with each remaining order.

      Considering that TaoBao and Adafruit claim they've got ESP32 series devices _*IN STOCK*_, what gives guys? Gifts at some point doesn't un-do or make up for what's being done here. You appeared to be the first shipping...NOW, you're the **LAST** ones.

      Nope. Email went out today saying they're cancelling all the orders and doing a refund. Whomever got the ones that went out in the initial lot are the only ones getting this one for the time being. I know I won't be buying any of them from them- I'll spend a couple of dollars more if I can source elsewhere now.
