This cable is a frustrating necessity if you have a Shure Wireless Guitar System and a guitar that hasn't got the input recessed.
Effectively the way I see this is that the product is necessary, and they have you cornered. It works fine, and I would recommend buying this instead of the straight jack WA302 if you usually use right angled jacks.
It isn't as long as the WA 302, meaning the wireless pack is attached to the guitar upside down if you don't want it right at the base of your strap, or want to avoid strain on the connector.
The connectors are not at all near to the quality of a neutrik jack, and I feel that they could easily be broken, if it were not for the fact that it is unlikely that you will snag the cable on anything (or stand on it for example!).
It is very overpriced (not specifically on Thomann, you will not find the cable particularly cheap anywhere!) but there are no alternatives.
A shame there aren't customisable/extra options on this.
