I had the AKG transmitter for a few years before I needed to replace the cable. This speaks very highly to the quality of the cable. As the cable is designed to reach from my belt to my guitar, it does tend to catch on things constantly, so the fact that it lasted a few years is pretty impressive. The transmitter eventually died, and I have since opted for the Thomann "bug"-type transmitter, which does away with the need for a cable. I would definitely recommend this course of action!
Got this as a spare - did a soundcheck then went to start playing - blank wireless! Cost about £400 so I wouldn't say it was a cheap one but it died and no-one seems to be able to repair them so after only 2 years service, it was binned. Poor show. Still, the lead was great!
