Does anyone have any experience dealing with the ductless mini split units?

[Jade Williams]

I have a 700 sq ft property that has never had any duct work put in or any A/C unit other than a window unit. I am trying to decide if the ductless units are efficient enough to spend the money on. I can't find any user reviews online about the quality of temp control. Any help would be appreciated. Also, this property is our "drop in" home. We only go "home" about 5 times a year but a family member will be occupying full time just to keep an eye on the place so not a rental or selling.
