DO NOT BOOK THEM TO CLEAN YOUR CARPETS. My mother and I did and when the carpets dried they were the same. The half star is for them showing up. Mum spent $100 and I spent $74, now we both have count our losses and call DRYTRON to come and fix the problem. That's what happens when you go for the cheaper option, It's my fault. I can only spread the word to so many people by mouth, hopefully this review will help people decide when they look them up.
