fitguru.ro review for SalesPop: Order & Sales Popup

Full of bugs. - I notified support about a simple thing, that the pop-up shows however you can't close it when you push the X like it should... nothing was fixed until now, several days later - meanwhile the popup window DOES NOT SHOW any more in any way, so a few days later it simply stopped working completely even tho' it's enabled. I am using a Shopify standard theme, Minimal.
