The overall quality of the case is reasonably good, as are a good few competitors cases at less money. I would not use it for air travel or regular transporting in a groups bandwagon but for travelling in a car on the back seat, as my gigging guitars all do, it is OK.
As to the poor marking of the unit, that is all down to Thomann who have a picture of the case on their product page which appears to show an angled body support pad which is absolutely essential for a Les Paul as without it the full weight of the body is transferred to the neck which is THE weakpoint on a Les Paul. Inside the headstalk cavity there is a support pad for neck which serves no purpose at all as it makes no contact with the neck or headstalk. It is simply glued to the base (rather badly) and my take on this would be that when specified to the manufacturer/supplier the support pad has been put into the wrong cavity and in stead of supporting the body it is supporting nothing at all. Quality control???
In my opinion, although a long time user of Thomann and pleased with all but a few of my purchases, don't risk your guitar, buy one of the other single cut cases that offer the proper support.
