We have used them for years now and have had no problems. When you call, you will hear that they will charge extra for more than 2 cans full. Well,every now and then we have to put out an extra can and they have never charged us for it. They always pick up what we have out there and are very friendly. now, they have ran into our mailbox a couple times...lol But that's minor. They do a very good job and you will be pleased! Prices are very reasonable also.
