I’ve had this thing for a few months at this point and it runs great! I’ve played all sorts of music sticking it to my locker in my dorm and even pulled a harmless prank playing meme sound effects when people grab stuff from vending machines. As long as it was metal it was good to go! I never did try the other attachments though.

These things are fierce!! Small but powerful and great surround sound when using two at different ends of a room!! Very cool! Well done!

I absolutely love this little guy! The resonance works best on cardboard, but it is a lot of fun to try and find what other surfaces resonate as well. I bought this to stick to the inside of my bus remodel, which is basically a tin can right now. It isn't as loud as I would hope, but works well for the size of the space. on most surfaces, this is about as loud as my phone speaker. on a cardboard box, this is significantly loud. If you plan to use it to dissect tone qualities in your audio, pass. but if you are using it to listen to music, audiobooks, etc. like most people, this is great.

The Bluetooth speaker part works very well. It isn't strictly necessary to peel the film from the sticky pad.

I would appreciate a supply of the sticky pads so I can replace them when they stop working. The controls are extremely small, requiring very precise motions. Maybe a stylus would help.

The FM radio is useless with these controls. Even with a cable to act as an antenna, the radio is "deaf". The mechanism for scanning for stations is cryptic. Do you give the control button a long press to start a full scan, or do you have to hold the long press until it's done? This is unclear, and neither seems to work. How long does the scan last? Seconds? Minutes? No way to tell.

The volume presses are nearly unworkable. With such a tiny button, fast taps are very difficult. Triple taps don't seem to do anything. It doesn't find any stations to switch between.

What is the FM frequency the radio listens to? In the US, where I am, it's between 88 and 108 mhz. Other countries have different FM frequencies, which might be why there's no stations being found.

As a Bluetooth speaker, I like it. As an FM radio, I would need more information on how to make it work. The instructions on the sales page do not seem to work.

speakers are really neat to have; they bring a sense of wonderment and experimentation to listening to music, since you can stick them on to any smooth surface, and they resonate with the character of the surface that they’re placed on. They have good battery life, and they’re good enough, volume-wise, for personal enjoyment of audio.
