Update: The flapper repair that Mike completed made the toilet run worse than it originally had. I asked that he come look at it and undo whatever he had done. He did not show up and made a flimsy excuse. It's very evident that the warranty and general service here is fraudulent. Be wary - I would never use this company again.
I had one toilet that was clogged, a second that was slow to flush so needed to be cleared proactively. Mike was very professional, clean and efficient. They were able to provide service in my condo downtown within a couple hours of being called.
In terms of why I would not recommend them again, my understanding is that the price was rather steep - $240+tax for a toilet snaking.
In addition, I asked Mike to take a look at the flapper of the toilet, which was not closing properly, meaning the toilet continued to run after being flushed. Mike was not successful in repairing that - the next day the issue was back.
