BUBBLE Portable Bluetooth Speaker Blutooth 4.1 3W Power Atmosphere LED Lamp Waterproof Dustproof Shockproof TF card AUX Blue

For the price, it's pretty good. But it's kinda a 'you get what you pay for' thing. The pros are that you can hook it on to anything so it's really portable. It's also meant to be really durable. I haven't tested how durable it is, but it's holding up to being used outdoors on hikes pretty well. The cons is that this little device talks when it does anything. I purchased this because it could work in both Bluetooth and Aux mode, but getting it into Aux mode is really tricky. The device seems to be temperamental. I read the instructions about 5 times trying to get it to go, but it seems to have a mind of its own. So I would say that it's not very user friendly. In the future if I needed another speaker I would not purchase this one.
