It looks pretty sturdy and, but I had to send it back 4 times.
The first problem was the XLR/Instrument connector. The "Click" part wasn't clicking in, so the sound came out way too low.
BTW, you need some strength to attach the adapter to the transmitter.
When I got a new one, it worked for a while but the lows were having a hissed/noise sound. Sent it back. I got the same one back because they couldn't find the issue.
This last one gets interferences (due to the 2.4GHz) that I can't use a wireless system on my Bass anymore.
If you play in tiny bars or are annoyed by cables, that can be the one to go, but not for big stages.
