Works perfectly
Disclaimer: if your evorina registers as another frequency than what's entered, don't fret, that's the machine accounting for inaccuracies, example: 266 shows as 266.24 which makes up for the inaccuracy, 2720 shows as 2727.27 (the 7.27 amounts to the percentage of inaccuracy)

Not sure if it works
No way to tell if it worked or not. No sound when connected to speakers. No support. I sent it back.
@**!
Not sure so sent it back.
If it had English on it without me having to decipher Chinese to confirm it's actually working I would have kept and spent more time with it.It has an earphone jack and if I had a powered speaker to check frequency output or a way to confirm the standard solfeggio frequencies I would have maybe kept it and made my own box for it.I just use a speaker now at my desk now for just trying to absorb some good energy.

Does it do anything?
Shouldn’t it vibrate or something in some way? I can’t see that it does anything other than light up. And no instructions or anything…Sending it back

Not accurate
I like the idea of the device however it will not go to many of those sounds exactly as you input it. If you input 963 it will generate a sound at 965.25. If you input 9999 it will produce the sound at 1000. If you input 2389 it will Produce the sound for 2396.16.
