Overall, problematic app, solves the issue if you want to have customized pricings for multi currencies. But the process to update each and every item is painful and does not work well with Facebook Channel. Also, if you prefer to be able to set your own conversion rates, this might not be the right app for you. Overpriced, and would rather have a different domain with shopify if I have to pay 29 a month with all the troubles.
Friendly and responsive customer service.
The app itself has not been great in our case (in particular due to inability of grouping countries into regions, which caused unmanageable number of regional product variants in the catalog).
Tried it out for 4 months, had a lot of trouble with it switching values from day to day and lagging.
