In all honesty, I have used Backer Camp several times for various Kickstarter projects. They are very responsive and helpful. I wouldn't say they are deceptive, just the opposite. Like most crowdfunding promoters they have become very helpful. Their staff is very good at what they do and I commend them for growing as they have.
I recommend them and that is from experience working with them on my campaigns. Like any company, they are not mind readers. If you tell them what you expect, they will deliver.
