Great Plugin and once set-up works really well. There are a lot of add ons (both free and paid) so you can add some great functionality to your webshop. However there can be a bit to getting it running well and looking good in your theme, so if you are not comfortable delving into basic code, or do not want to get a developer to help, you may have a few basic issue. However all these are typically very easy to sort out, and most users/developers will be able to sort theses out very quickly. I have been using the plugin since it was released, and it has come a long way and continues to get better all the time!
