First suite changed before covid due to fault but no big concern, since covid rules relaxed we started to use the patio suite with friends and family and found with moving furniture seating back and forth it was leaving black score marks all over the patio that always needs to be jet washed out each time. Tried talking to Kettler several times and sent them video and pics but they dismissed my complaint as not a fault. We have also a Hartman suite for 10 years with no marking from similar feet but this did not interest them. Good looking product but dreadful service and poor attitude from customer department and now we have to find our own solution- my advice? Buy a different make.
