This has turned out to be one of those deals where you don't get new features. To be honest, had I known that the developer would want to charge big bucks for newly added features (added pretty much immediately after the deal finished) I wouldn't have bothered with it.
Also, and I really don't know how or why this could be, but my organic site visitors have gone down since implementing this. I don't know how I why, but I think I am going to have to go through the hassle of removing it and just assigning it to the junk cupboard of deals that didn't work out. Luckily, I've had some great deals too so that odd dud is to be expected. You have to kiss a few frogs to get a date with those princess deals :-)
