We chose these guys because they had the lowest quote, the longest service plan, and the lowest yearly opening and closing rates. The sprinklers work great. Whenever we've had a question or problem (like my husband taking out a sprinkler with the lawnmower) they show up often on the same day and I never see a bill. On top of all that, they're the nicest group of guys you could hope to meet. I recommend them whole-heartedly.
