My order consisted of 4 windows and a pair of french doors. The windows were of a simple design made accurately and well finished no problems as yet. The french doors are a different story. The corner mitres of the outer frame had unacceptable gaps and had to be returned. This was corrected but took a couple of weeks. On fitting, the doors had an alignment problem. it was not possible to correct with the minimal amount adjustment available. I was told this was a Aluframe profile design fault. To Rhino's credit a full remake of the door set was offered along with a fix by modification and a guarantee that the fix would be a permanent fix. As I am a reasonable person I opted for the fix which was carried out succesfully and I now watch that space so to speak. Sorry Rhino only 3 stars but not a good experience overall and I am still not 100% confident in the longevity of the doors.
