We had lawn envy from our neighbor's yard, and eventually decided to pay the extra money for Chemlawn. Wow, did it work immediately! They come 6 times a year and spray different treatments on the lawn. They always call in advance to schedule, and they will spot treat lawn weeds that are particularly pesky. The service reps have always been friendly. The only negative is that they are a little pushy and have tried to upsell us to additional services.
PROS: Great product
CONS: A little pushy
