I've never experimented with anybody else, as I've used Brenda's Cleaning Personnel for 16 years. Rating them is very difficult, as the people I have currently are excellent, but others I've had to train to clean my home. I had to explain to them how I wanted them to clean it, and some I actually phoned about and requested that I never see them again. But again, the people I have right now are excellent, and that's why I've continued using them for as long as I have.
