I play with bands as a guitarist, so I have to take my guitar with me almost EVERYWHERE. That was the hardest thing ever with the hard case that came with my guitar, which I got from Thomann aswell! So far, it has been the best sleev-case I've ever used, for many reasons, which I will list below, as pros and cons.
Pros
1. The padding inside is so amazing, I could sleep in the case. I once dropped my guitar while it was in the sleeve and it I it was like landing on a bed. Also, in the bottom of the sleeve there is padding aswell.
2. There are handles wherever you'll ever need one. And the quality is excellent (on the whole thing)
3. There are straps, so there is no problem riding a bicycle with your guitar on.
4. You can put your keyring on!
5. Quality is amazing!
Cons
1. Even though it works most of the time, the metalic thing that closes the books case might get stuck on the belt.
2. Inside the case there is a small pocket, which is too small for what I use it.
Overall, I give it 10/10!
