I've been using Kaseya for approximately 5 years and it is by far the best and most mature RMM tool on the market. They have had their occassional issues with new product releases but that is to be expected with any large software platform. The key to Kaseya is its fully integrated nature. It's not just a bunch of bolt on products but is truly one platform. I have been able to grow my business without having to add head count and my techs love it. I have evaluated all the products, including some of the new ones and they don't compare.
