Service is less than one would hope; we run very low on product before restocking occurs and when there is a problem (some of which recur) they show up in a day or two. The deal breaker was their decision early this year to cease paying commission if your machine's income falls below an undisclosed amount. They NEVER contacted any of the customers affected by the change. We found out when we called to see why we didn't receive our check. Unacceptably unprofessional! We will not continue doing business with Sky Top and do not recommend them to anyone else!
