Bid ceiling for keywords did not exist when we tried the app, combined with horrible customer service we ended up with nearly 10k damage. We moved to Ignite by SellerLabs. Highly recommended. With Ignite I didn't yet needed a customer service, so I cannot say much but I do know from friends they are reasonable. However the app is much more accurate with information, and one of the greatest benefit they have is the keywords data base,a unique tool that they have from Scope, a keyword tool that is integrated to Ignite and provide you greater value.
