At around 40 Euros it does not come cheap at all, could get many accessories for the price of this bag. However, if you own a THR, this is extremely useful in transporting it around without a scratch. It is padded well at all sides and comes with a strap.
Pros:
Enough compartments for cables, power supply, and even small accessories like picks, string sets and capos (side pockets).
Well Padded and strong
If you have a THR5, it has 2 strong connectible velcro pads to size it correctly, leaving plenty of extra room for more guitar stuff.
Cons:
Expensive
Handlebar exposed, which is good for carrying without the strap, but bad when raining.
Overall a great buy if you plan on moving around with your THR.
