I have found this Bergerault gong stand to be very well-built and easy to mount. The stand is very large (2m x 2m), so it could have been a stand with tricky stability. But, after mounting (and playing) five gongs (22"-30"-26" on the top floor / 32"-30" on the bottom floor) I can assert its stability, which is a very nice surprise. The built quality of the wheels is good, making it easy to move, even with the gongs in place, and overall this stand produces an impression of sturdy construction.
The icing on the cake: when playing the gongs, I have never heard a noise coming from this stand, which is often a problem with other gong stands. Good point for Bergerault here.
In summary, I would definitely recommend this Bergerault gong stand for serious work (orchestra), because it seems to be a fiable stand, very well-thought and constructed.
