Initially BBPixel worked well. But then we tried to integrate VirtueMart (shopping cart for Joomla) and we had lots of issues with the user login flow.

Also, BBPixel hijacks Joomla's user management, so you cannot use Joomla extensions like Community Builder.

So, we uninstalled BBPixel (which was not a trivial task since they modify quite a number of Joomla and vB core files).

Managed to get VirtueMart up and running, but it was too buggy. So we ended up integrating ZenCart, which is what we are using right now.

We have thought on redeploying BBPixel again, but we have delayed doing that.

We also researched the eLearning plugin, they have two versions, with and without Community Builder support. We couldn't find enough feedback on their product, which is why we went with BBPixel.
