When we unpacked them the quality shows immediately. 
Well built, the rollers are big and heavy , very nice fit and finish 
When we put them up I was concerned about the wall not being perfectly plumb but as we put them up we found lots of adjustment in the rollers and the top bar wall brackets 
We love these doors and would strongly recommend them to anyone .
Just make sure to have 2 people at least to handle them and follow the instructions
