Cheapest reliable wireless system

I have been using this for practice at home, rehearsals and even an outdoor show recently. It performed flawlessly, no issues whatsoever. Sound-wise it seems to have less noise than cables, even the more expensive ones I have, overall great clarity. Worked perfectly for the advertised distance and only had an issue once with a lot of metal equipment and a wall between the units.

I did not encounter the issue some other commenters had with active pickups (EMG), even though I plugged in a fresh pair of 9v batteries.

The build quality is not that impressive as it is all plastic but perfectly reasonable for this price, looks fairly sturdy.
