GBGood for scaling ads Pretty fair pricing model, and they have a lot of technical knowledge about ads for Facebook. They are also guest speakers on Shopfiy's webinars here and there, so feel free to watch their webinars first before testing the waters.

GBWorking Out started working with these guys a few months ago. it was pretty rough first few weeks with really low ROAS, but it picked up after the 4th and 5th week and were profitable now. Things are going well now and we're happy with the return on investment but wish they did a better job telling us that is was going to be slow the first few weeks. Other than that recommend.
