    • Such a great speaker!
So I bought this speaker for an event. Used it once and put it in the basement. About 7-8 months later we start a renovation and I wanted to play some music - and found the speaker. It STILL HAD BATTERY. I’ve now been using it daily for the 4 month project. It has excellent battery life, GREAT crisp sound, and very surprising deep bass out of such a small unit. VERY, very satisfied with this product. Finally a purchase where I feel like I actually bought something for much less than its value. ... show more

    • Great Deal Highly Recommend
Well, I've only had it for a day.But so far , i'm really impressed for the value. The sound quality is good and it actually is loud enough to make my kids cover their ears!!! Going to buy another just because this things awesome. 9/10 only because it doesn't come with a wall charger but it does come with USB cord so not too bad. I would say quit debating and buy it already, you won't be disappointed. ... show more

    • Great little speaker that functions well and packs a punch
I wanted something to use while playing volleyball with my friends outdoors and didn't want to spend much money but have it sound decent when the volume is turned up to hear on two courts. A little bit of bass and clear sound when turned up and I'd be happy. I'm pleasantly surprised with this little guy as it sounds pretty solid even at higher volumes. It's about the size of a coffee maker and the multi colored lights are a fun extra. It sounds good through bluetooth or connecting an aux device (like an ipod for us old timers that have been collecting music since the 80s!). Just don't make the same mistake I did by plugging the aux cable into the mic or it will sound terrible since they are the same type of plug. I like the little device stand that snaps on the top but it's a poor design since then the handle gets in the way, so a little hard to have both which might mean that the stand doesn't last very long after it's snapped on and off a few times but I'm able to carry it short distances with the stand also in place so it's not a big deal. The only negatives might be that I don't see any change with the equalizer or "inside/outside" settings. I think they are a gimmick honestly. It also took several hours to charge initially so we'll see how long the battery lasts and if that's normal. On a full charge it lasted about 15 hrs. In summary, if you aren't a sound snob and just want something that is small, easily portable, connects both bluetooth and aux and sounds pretty decent when turned up, this is a great choice for the value. ... show more

    • I REALLY Wanted To Love It...
The media could not be loaded. First of all, the pros: As far as the sound goes, this is EXACTLY what I was looking for. Speaker has a deep bass and good tweeters (the side mounting of the latter makes for a really good surround sound quality). I've had no problems with bluetooth connection despite what other reviewers have complained of, nor do I understand the one reviewer who said that returning things to Amazon is painful. I've been a Prime member for over 10 years and I've NEVER had that problem. All returns have been quick and painless. The FM radio works fairly well. It gets a few stations that I know are on the dial in my area but doesn't get at least one that I am aware of. I'll try it outside a little later to see if reception improves. The AUX line works well. I've connected it to my phone and tablet headset jack and played music with no problem. But, the problem is that the cons are major! They are these: Neither the TF card nor USB flash drive I've tried played any of the music on either device (video attached), though I can play from either source when attached to my laptop. This is important to me since I desire the freedom of not having to have my phone connected in order to play music. The final concern was actually something that I thought I could work around -- the seemingly fragile charging port. After all, if that fails, the speaker becomes useless. Now I've had no issues with it as yet, but the fact that a number of others (per the reviews) HAVE had the problem is a con to me. Before realizing that two of my music sources didn't work, I had thought I would get the seller to agree to a limited replacement warranty (10 years or more) SOLELY on the charging port and I wouldn't return it within the 30 day window. But, sadly, I have to return this one. But the good news is that I've seen a similar one with a comparable price here on Amazon that I'll order on the same day (today) that I return this one. Hopefully, I'll have better luck. EDIT: Well, the similar one didn't measure up. I thought it had separate bass and treble controls, but it didn't. I sent it back. I tried a different one and this time used the "Ask Rufus" feature about the controls. "Rufus" told me that - based on two customer reviews - IT had separate bass and treble controls. It didn't, so it's going back as well. In the meantime, I canceled my initial return for this one and restarted a return, opting for a replacement instead of a refund. Initially, I had the same problem. Neither TF (microSD) nor USB slots played music. So, I thought that maybe I had the wrong type of flash drive/U-clip. I then used a USB converter drive that many of us used prior to laptops having separate microSD slots on the side. I put the microSD card in the adapter and inserted it in the USB drive and music played. I later wondered if the microSD card I was using has simply too large. The one I was using has a 128GB capacity. I used one that was 64GB and lo and behold, the music played. I'm now KEEPING this one and the only reason I didn't change my rating from 3 stars to 5 stars is the issue reported with the charging port. That forced me to spend another $6.99 for a 2 year warranty, since my contact with the seller about the limited warranty solely for the charging port fell on deaf ears. I've yet to hear from them. So, the bottom line is that I LOVE the speaker but will never by from the seller again. I just hope that it holds up... ... show more

    • Good Programable Sound with Powerful Bass
Excellent sound, power, volume and EQ control. Can deliver a powerful bass by either selecting a preset or manually editing the low end. High end is adjustable too. Be gentle plugging in the power supply. On my first unit, I wound up pushing in the jack so I purchased a second unit and am more gentle with it. I found this unit to be superior to other brands including the Tamproad which I would not recommend. ... show more

    • Good sound -- Not reliable
This is a nice little radio with good sound. I was initially happy with the purchase, that has changed. The issue is: (1) It will flip from FM to other functions, like bluetooth, on its own, which happened almost immediately after purchase. (2) It shuts off on its own - not at first but now frequently. You can't depend on it, very frustrating! I turn it on when I leave the house for my dog, to come home with it off!!! I would NOT recommend for these two reasons. ... show more
