My first guitar strap so this is a beginners point of view.
I wanted a strap so i could practice standing up, as a beginner i'm trying out all the various techniques to find my style. So i was browsing Thomann, as you do, and came across this strap.
Decided to order it and even though we are all dealing with COVID-19 delivery was quick. The strap feels very high quality, the fabric feels like it can take a beating, while the embroided design looks really good, even better than on the pictures. To attach it to my guitar i did have some difficulty as it was a very tight fit, i expect this to get easier over time but do be aware of this as it can be frustrating when it seems like it doesn't fit.
When it's fitted however the guitar is not going to fall of, if you are afraid that will happen i believe you can by straplocks.
My only negative would be that the strap is not super grippy, so depending on what you are wearing it might slip of your shoulders a little bit.
Overall i would recommend this strap, and would buy again.
