We had a very mixed experience. If you get a good tech then it seems to go well - but there is very little back office support and management of the techs so the service is disjointed.
Also be very cautious about buying Appriver through Wizard. Appriver is the best hosted exchange product out there - flawless. Wizard add no value to the product and refused to allow us to deal directly with Appriver even after we fired them as our IT services company. Because we buy Appriver through a reseller, we are not allowed to call Appriver's free 24/7 support. Instead we have to call Wizard during business hours, where they are liable to charge us their normal hourly rate. Don't make the mistake we made - buy Appriver directly.
