2.4GHZ WI-FI controller MIboxer Led strips

Anyone know or tried these led strips controllers with remote?

Obviously they are for limited loads but they have many outputs with the possibility to mix colors or CCT
I can not find anything about the pwm Frequency or photos with case opened.
But from the videos the flicker doesn’t seem visible.
There are dozens and dozens of remote controllers on Aliexpress.
This increases the confusion .
Feel free to post if you know better models without at budget price
thanks in advance
