Extremely pleased with the level of service - prompt, professional, and always the right fix. They have been extremely patient and knowledgeable in my quest to customize the cart. I also made the switch from the other extension using opencart and not regretting it one bit. The migration went well, though I did have to copy over my theme. I found it helpful to to keep a version of my site with the old shopping cart so that I could compare, fix or carry over any tweaks that didn't make it in the migration.
