Compact, waterproof, loud enough sound for what it is (I rarely have it at max volume bc it's too loud)- I use it also as a speakerphone Bluetoothed to my cell phone and it works very well - so no need for headset, earbuds etc when using this. No adjustments to bass, treble, but you can't expect that for $17. I'm sure there are crisper sounding speakers with better treble and not as muffled like but they cost 4x more. charges very quickly and holds the charge for hours (manual says 9 hours or so. comes with charge USB plug) Factoring in the price this can actually be 5 stars. can't beat the quality overall for the price.

The size and shape is just how I like it, the sound is pretty good

I over oall like itit has been the best thing i have got so far inlike how the water speaker keep playimg whyunderwater

Okay little speaker. There aren’t buttons to skip or replay songs, which is why I gave it 4 stars. I mainly use this in the shower, the battery last a decent amount of time and it’s small for traveling. Used it at hotels and pool side as well as taking the dog for a walk and it isn’t cumbersome

This speaker works great for my car as way to listen to content from my phone, as well as a hands free device. Easy to use, fits perfect in my cupholder. Simple volume and phone controls on the speaker make this a great fix if your vehicle doesn't have built in Bluetooth.
