The doors were recommended by Liam of Oakwood Garden Rooms and I chose these doors partly because of his recommendation but mainly because of his superb video - https://www.youtube.com/watch?v=vSAW5r5rQsg. I couldn't have fitted them as a first-time door-fitting-DIYer without this video as the instructions that came with the doors wouldn't have been enough and were not particularly related to the garden room pre-fabricated doors that I bought where the doors are set on the OSB board floor. I contacted the help desk on several occasions and the staff were very helpful. I think it would be worth making clear that it is the small orange label, rather than the large white label, that goes on the inside. I didn't see the orange label initially - I am 75 and perhaps my eyesight is not the best! I didn't have to do any adjustments as the doors fitted perfectly. I am delighted with the finished fitting; the doors look great, glide effotlessly - they passed the one-finger opening test! - and I would recommend them.
