I'll buy more for _my use_.
Pros: reasonable price, RGBWA-Uv color mix, silent, good assembly quality.
Cons:
1.could be not enough light for many users, but you can buy more fixtures with price.:)
2.There are visible color differences on the edges of beam, as for any cheap mutlicolor fixtures.
3.Strobo mode is completely useless if you want to change it gradually (i.e. not static mode), whole range (0-255) is split to three range modes - very difficult to use it as channel value with fader (value remap needed).
When changing strobo value - every value change causes strobo timer reset, so while you are moving fader fixture "stutters", instead of gradually change strobo speed. Only chase/sequence defined at console can provide workaround (i.e. implement stroboscope/shutter your way programmatically).
4.This is pure 8-bit fixture, so changing dimmer with non-equal mixed colors start to change preception color because 8-bit rounding error, when multiplying 8-bit dimmer * 8-bit color value and output is also 8-bit.
So I use just 6 channels mode (no dimmer, no strobo).
5.Not very convenient cables outputs - to the sides (inputs/outputs - up/down). On trussers looks like spider, if both inputs and outputs are used. :)
