I use on my cart virtemart 2.0.8 in joomla 2.5.6. O first found the install a bit clunky however I then gave it another crack and it installed OK. Overall I was impressed with the payment shipment workflow compared to other process driven. Will need to test it out a bit further as loading extra extensions seams to be a bit buggy. I like having the option of one page or multi page check out good to have choice.
