This is a simple wireless system, and as good as you can expect from a unit this cheap.
Yes, someone would say, the built quality is not top of the line. But that´s the thing, you can´t expect top quality for that price.
Yes it feels a little bit plastic, but that doesn´t bother me.
The system itself is very easy to start up, almost plug and play level.
It also doesn´t color the sound that much. I have some top level cables I use and I didn´t hear any specific differences between the sound with cable and this wireless. Maybe if you want to analyze extremely critical, the sound is maybe a little bit brighter than with good cables.
But that can also be that the cables are coloring the sound....
So my conclusion is that this is a good semi level wireless, good enough for practicing at home or small cover bands who doesn´t play on too big stages.
And because the system itself is so cheap, you can easy have another backup pair, and it will still be a very cheap and affordable system. That said because battery life is not that top level.
So if you don´t need a big wireless system for Pro use, I can without problem recommend this one. You get what you pay for.
With this system I can say, you get what you pay for but 20 % better.
