We didn't reach that point when I signed an agreement with them for a car rental. They requested a lot of paperwork and asked for too many details from my side. Looked suspicious. But after reading reviews here, I think I did a good job of avoiding them.
I attended physiotherapy there after my injury (my leg was broken). The trainers are real professionals, and they find an individual approach. After a couple of weeks, I forgot about this dull pain I used to have. They suggested some exercises and yoga asanas, which were really effective.
