Every month I have the Sunrise Support Staff go through my desk top & remove junk files & other items that may hamper or slow down my computer. I have no complaints. Whenever an issue does occur, such as an occasional crash issue. The Sunrise Staff gets on it & resolves the problem. I've had my unit for almost 4 years, and she runs as quiet as a mouse with fast response etc. In fact these are the only group of techs that I don't have to worry about anything of major proportions going haywire on me like a lot of other *** out there on the market. If the communication is just so will it be with your mechanical items. Most of you probably don't know how to maintain your unit for only having you to blame why it don't work right. Your alright with me Sunrise.
