## Customer Reviews

### ⭐⭐⭐⭐⭐ Works perfectly
*by R***. on October 29, 2024*

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
*by T***B on November 28, 2024*

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.
*by @***! on November 17, 2024*

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.
