This little gadget does exactly what it promises—clean sin and square waves, no drama. You can see from the pictures (because who doesn’t love proof?) that it delivers. I cranked it up to 90,000Hz, which is either really impressive or just an arbitrary number I decided to test. Not sure what the actual max is—maybe it stops at "too high" or "you’ve gone too far, buddy."No directions included, but if you can press buttons and possess the patience of a person assembling IKEA furniture, you’ll be fine. Just punch in your frequency, hit “OK” (bottom left button, not a self-destruct switch, I promise), and voilà!Will this make me feel better? No clue. But does it faithfully spit out the requested frequencies? Absolutely. And really, that’s all we can ask for in this chaotic world.

This resonance generator is simple to use and works exactly as described. Just plug it in, set your desired frequency, and let it run—no complicated setup required. The signals are clean, and the screen has a backlight for easy visibility. It could be a placebo effect, but I feel like I’ve noticed a positive shift in my mood when it’s on. I’m excited to keep continuing to play around with the frequencies!

This item is thin and easy to use. Plug it in and it will automatically turn on. There is a switch to turn on the backlight on the screen. If you want to switch the frequency, the buttons on the panel can be customized. It is very straightforward. It’s something that I plug in and forget about throughout the day/night. So far, so good!

To be honest, I don't understand the science behind this instrument, but it does seem to be helping me feel better. I'm more upbeat and confident when this is running in the background. I recommend giving it a shot!

Notice nothing. No improvement, the thing doesn't make a sound, how would anyone know it works?

I just received this so just started playing with it. Comes with no instructions. As stated the default frequency is 7.83 hz as a sine wave. To input a new frequency you need to press mode switch then new frequency, then okay switch. I am guessing that this frequency is transmitted to the PCB antenna, sine, square, and reverse square circuit board "holes". My application is to dial in a frequency, have it transmitted to the PCB antenna and have the antenna transmit it to a room. If you want a device to inject a frequency as an input you are better off with a device with a BNC connector and switches for wave form.

I was very disappointed in this. NO INSTRUCTIONS. Was promised on 3 different date. I’m not sure how to use it so it’s collecting dust
