This is maybe one of the best extensions I used over the past years and I use a lot. I was surprised about the possibilities and fast import. Had one problem after importing but owner helped me out within a few minutes after sending a ticket. This extension is a must for everyone having a Virtuemart website with lots of products. I was the most surprised to find out it is even possible to create attributes and options for the bulk of products which should me imported and this makes this extension "two in one": you can even use it as a "Bulk attributes and options importer". Thanks!
