I have two variations of these instrument cables and they rock! Just like Thomann :-)
This one is used for guitar having jack insert like a strat does, while the other one is with angled jack for different guitars. In comparison to less expensive Snake and Cordial that I have, this is noticeable difference. These are sturdier and to a degree less flexible, so there is less chance of damage if you plan to jump around when playing. That was not my initial intention because I tend to jump around in different occasions :-) For me more important was the fact that the shielding is much denser than with cheaper cables. For home use cheaper instrument cables usually do the trick, unless you have more noise like me. In one room cheaper cables can be used and I was very happy with those, but when I moved my toys to another room I needed more shielding and Sommer does the trick.
