Variety of function settings: It is equipped with a color screen display, which can display the waveform/time frequency/volume, as well as a pitch indicator and a corresponding piano pitch display, and various function settings can be realized through the panel keys.
Many Voices: There are more than 70 kinds of voices for you to choose from, including more than 20 kinds of traditional Chinese national musical instruments. It's extremely playable and perfect as a gift for a friend.
Self-contained speakers and pluggable antennas: In addition to connecting to audio equipment such as headphones, it can also play sound through the speakers that come with the host. When the audio device is connected, the external speakers will be automatically turned off. The equipped antenna can be unplugged, stretched and retracted, and it is very convenient to store.
Small appearance, easy to charge: The overall appearance is small and exquisite, easy to hold and play. Powered by Type-c interface, you can play anytime and anywhere by plugging in the power bank. It is very convenient to use and has a high cost performance.
Warm Tips 1. Because the antenna is small, you may feel that the piano is not sensitive enough. You can buy a large antenna (3.5mm), or connect the original antenna to a metal sheet or metal rod to increase the control range, or directly press the metal block on the original antenna. 2. The pitch control will be relatively stable after the instrument is turned on for 5 minutes.

As mentioned in the title, the tiny size is pretty impressive. And it works the way a theremin is supposed to work. However, despite having 40+ sounds, they all pretty much sound the same. The biggest drawback is that this unit is pretty useless as a musical instrument. Frequency control over the notes is way to erratic - you get a 1 octave range within 2-3 cm of the antenna, and then a 2 octave jump in the last cm. A range / sensitivity adjust exists - but all it does is lower the bottom note of the range and you still get that same awful jump in tone near the antenna. I wasn't expecting a miracle from this little gadget, but I think a smooth range of musical notes is the bare minimum requirement.

As the seller states, the antenna on this device are small (in order to keep it compact). Larger antenna would give better control, but it does have both volume and frequency antennas and it does work, although the hardware interface requires some tinkering to understand how it works. Essentially, one antenna controls volume level and the other controls frequency, with louder/higher output the closer your hand is to the antenna. You can choose from probably over 100 baseline sample settings, from straight pitch/frequency to more complex ones that emulate traditional Chinese and other instruments, including those that limit output to musical note tones. It has the full principle of a complete theremin, but lacks echo/reverb/tremolo /fade effects that are necessary to be a complete theremin. Considering the size, which is not much larger than a man's wallet, it's a great value for theremin fans. I think if you could connect it to a mixer app, you could get a full theremin using this device. Haven't used it much so cannot speak for how long it will last, but electronic subcomponents appear well connected (soldered) and mosfets have appropriate heat sinks. I like the clear cabinet which allows you to see much of the electronic components without disassembly.
