I waited to write this review until we could really see how this speaker holds up. After 6 months of wear and tear (my husband is pretty rough on speakers bouncing them around on the back of the Gator) this speaker is holding up great. The Bluetooth connection works great. Although is is a bit heavy, this adds to its value. Great size and great price. Sounds are clear and the design is great. Might get another!

Love the sound ! I wise it for baseball league and for the price it is amaaazzing quality and a great way to hype up any team it's not going to be heard across the ballpark put it does what it's supposed to for walkup and keeping our team hyped ... Also I use it as karaoke in the house in a more moderate level of sound lol

I have 9 different Bluetooth speakers, each offer theyre own features and the sound quality varies among them. I had seen ION before but not tried nor heard the units. I was pleasantly surprised when I got this one... it sounds great and has many good features, its sturdy and I am so glad that I can play USB thru it. It packs a punch even at low volume levels. As soon as I can I shall buy a second one and pair them. Highly recommend this brand and this ION unit

Probably the best portable stereo you can find. Pros: Powerful and good quality sound (after tweaking equalizer settings). Seems to play up to 1153 mp3's on a USB thumb drive while the other jobsite stereos don't read a thumb drive and only charge other devices. Contains a huge battery core. You can blast at volume 14-16 for about ten hours and still have 2 of 4 bars on battery life. Cons: Randomization sucks. With over 1000 songs, it seems to play some everyday, and sometimes the same song up to 3 times a day. But when it's playing such a song and you want to hear others in that folder, switch to folder mode, and it will play that folder in a loop until it getting back to the song it started on which you can skip. Set it back to random and skip to other stuff. As you add or subtract files from the drive, it'll change which ones that stereo tends to play a more. With the 1153 song limit, you'll run into that before you reach the 16GB limit, unless you have whole albums as single files. Adding too many songs slows loading and makes it studder at first. So I just divide my collection over two thumb drives so far. Have 32GB drives, but 1153 mp3's while most are ripped from CD at max 320kbps quality, only takes up about 8 GB. Only plays mp3, not wav or OGG. Didn't try flac but the manual only mentions mp3. Does anyone use that garbage wma format? I don't. Other info that may interest people: In the equalizer settings, I turned highs and mids up 3 and bass down 1, and bass is still higher than normal. With the default settings, mids containing other instrumentation and other layers of sound get drowned out. Haven't tried the phone app yet, which has more equalizer options. Weighs 16 lbs. Has wheels and extendable handle. I just carry it by hand. Has both size input jacks and comes with a microphone. Only used the bluetooth a little, and haven't bothered listening to any radio, since I don't want to hear any commercials. Overall, quite happy with this stereo. Have had it about 9 and half months at time of this review.

Works great! Great sound and battery life!

Play Video Great speaker. Great for large events. Has wheels and is portable. Comes with microphone if you need it. Connects pretty easy to multiple devices. Water resistant and durable. Very sturdy

Bought this one after a lot of research... glad I bought this one. Got it for my wife's photo shop and she loves it. If anybody wonders if it will sound good... you will be amazed!

Awesome sound
