Tiny but mighty
I absolutely love this portable speaker! It’s great and easy to travel with, it doesn’t take up space and the battery life is perfect on it. I have a 1B1B apartment and the sound fills up the entire space. I also use the speaker at the pool and beach it gives plenty of sound and bass!! It also comes with a charger so you don’t have to purchase one. Best purchase ever!

Great for laying in bed, listening to tunes.
I love this little device. I can pair it with my phone, tv, ipad with ease and listen to music or shows. It has a long battery life and sounds good. My only cons are it would be better if it said what percentage the battery life is at instead of just saying normal battery level. That and the normal sound mode has a little too much bass.

Compact and good sound
Easy to pair. Good sounds. Compact. Controls are easy to find. Mine do not come with a charging cord but I have a dozen so that was not an issue. I use this to boost my TV speakers while doing treadmill workouts. I place this in the water holder and it prevents blasting out the house.
