Revised review. Yes a brilliant plugin but you need the paid version for it to work correctly, so buy it and save yourself hours trying to get it working.
Support and documentation very limited even for the paid version which is very disappointing.
If we offered that level of support to our hosting customers, we would be out of business! I get the impression this is a young company with very limited retail experience, caught up in the typical 'get back to you in 48 hours' mentality.
Oh yes, no support on weekends either so do not install it on a Friday just in case you cannot get it working.
I hope to be able retract this review if this company lifts its' game!
