This gong stand is interesting if you need a stand that can be easily unmountable and, because it is sizable, you can make it fit gongs up to 40" in diameter. Good if you need to travel or have limited space.
But, the downside is that, in my experience, it is not so well built. It is relatively stable, but when playing a gong, wathever the size (I tried 22"-38"), the stand makes some noise, which is disrupting. For me it is the one disappointing point. Maybe one could better secure certain pieces which cause the noisy vibrations, but I have not managed to do so in my case.
So I would summarize as follows: for the price, this gong stand is good if you travel, good if you have not so much space and need to fit different sizes of gongs, good if you need an extra stand, BUT not so good for serious gong work.
