Decided to go for Origin Bi Folds over over competitors as they appeared to be great quality. The reality is they've been nothing but trouble and the local installer has been equally disappointing. Main door lock mechanism broke apart almost immediately, took 6 weeks to get replacement parts, the main door never closes properly and has now caused damage where it's been rubbing and knocking against the aperture, some days we cannot even close/lock the door so have to leave the house unsecured, takes days for local installer to come out and then cancels on the day when I've had to have time off work (again). Six months in and still the "premium" product we've bought isn't fit for purpose and I'm facing more waiting around for someone who might be able to sort it. Origin needs to take more responsibility for the actions and approach of it's supplier network.
