I completed 5 this weekend. Its about 36-40 photos per store, but no one bothered me. Its a ton of photo uploading - took me about 30 minutes per report. The interaction with an associate is pretty straight forward, you are just asking their opinion on two types of tech wearables. All my locations were big box retailers, and the employees weren't really 'tech experts' so the conversations were pretty brief.
At $50 a pop, they are priced about right. 20 minutes in store, 30 minute report, drive time.
One thing I did was I looked up the item location in the store and took a list with me. It made the photos much easier. They are groupe by - headphones, gaming consoles and wearable devices. Really pretty straight forward.
