AdParlor allows my small team to move quickly from concept to execution. We no longer need media sheets or need to spend hours in Photoshop to develop multiple versions of an ad.
Adparlor is very easy to use and it makes creating multiple versions of an ad easy. No longer do you need to remember copy length, image size, etc. It's all built-in and functions seamlessly between ad units. We are a small team in a large organization. This saves us time when developing mock-ups for ad campaigns.
For what we use AdParlor for, I don't have any issues with the interface or the functions.
