5 of 10 POORLY soldered
Seem to be ok so far, but 5 of the 10 had poorly soldered pin headers. Pin headers weren't fully seated and several were at angles resembling a ski jump. Not as easy to fix as you'd think - requires heating all 8 joints to reseat header.

Very Old Version of AT software
Beware, these come with a very old version of the AT software, 0.21.0.0 and SDK version 0.9.5. Current AT version that I am aware of is 1.2.0.0 and SDK version 1.5.4.1.So if you've been using these chips before you will probably have to reflash them to new firmware as they probably are unusable otherwise.

Received ESP-01 not ESP-01S
The description of the product, the picture, and the bag they came in said ESP-01s, but I received 10 ESP-01 modules. ESP-01 requires extra supporting circuitry that makes them useless in my project.Edit:I tried ordering the product again in case a mistake was made. Still received ESP-01 not ESP-01s.
