User Reviews

It does seem to work fine but it does make the CPU, GPU and memory work much harder. Mine adds 10 degrees C to the CPU. The GPU use goes up by 8% or so. CPU use 12% ish and memory grows by nearly a GB and gets larger over time. I wonder if this can be improved.

Works exactly as intended and fixed the audio delay on my bluetooth. I like the simple UI too.
