I signed up with ChannelGrabber in April 2013. Things may have improved.
I was given a whistle stop tour of the system - shown how to attach to 3rd party Amazon listings and told that was pretty much all that was required for any type of listing on any market place.
There was no trial period - the rationale was that it was necessary for their engineers to import my products at my expense before the system could work, therefore a trial could not possibly work. So, I committed, paid the up front monthly fees, plus data import, etc.
I found the system to be seriously buggy, unreliable and slow. My earliest stock items had many variations, and their screens for setting up variations were so difficult to use that mistakes were virtually inevitable and very hard to fix - especially if you'd uploaded / attached to Amazon listings.
I persevered for too long with it, but at the point of leaving I did raise my issues with the CEO who basically dismissed them all out of hand.
The experience with ChannelGrabber had a seriously negative effect on the business - could not sell properly and the money paid to them was a significant chunk at that point.
