Recommended!!! I like this speaker because of way it fills a space and the loudness it has for its size. Perfect for small outdoor party. If you get 2 then surround sound is even better. I do recommend buying refurbished as you can get 2 for the price of 1.

Floating this in the pool is silly unless you are the only one using the pool and you are not splashing much. Depending on how much you wet the device it will decrease the quality of sound significantly. You'll need to dry this out to get optimum sound quality again. When dunked in water it sounds garbled until the water has vibrated out of it but don't worry as long as the rubber protector for the ports is fully inserted no harm done.

If you are looking for bass then you'll have to pay the price difference and get one of the larger cylinder shaped models... Logitech UE is great for surround sound! Using the App you can pair a couple of these to get the full benefit.
I have used this speaker for going on 3 years and it still provides long battery life and good quality sound compared to other speakers of its size. It is great for beach or camping trips. Literally indestructible unless you are trying to damage it using extreme methods. There are plenty of videos of different things that have been done without damaging the UE.

Full rich sound in a surprisingly light package. The shock cord clip allows this to attach to a belt, backpack, door handle, or just about anywhere you are. Quick to charge and easy to use. I use it while walking, fishing, or working around the house. I've gotten it wet twice with no issues. Once on the outside of a daypack during a heavy rain and the other fully submerged when I knocked a pack into the stream.

I spent eight hours yesterday cleaning out the basement storage room. I hung this on the wall and started the music. Great sound all day long helped a dreary task go more quickly. You can pair multiple phones with it and switch off songs or playlists.

Another feature I like is that if you press the up volume and down volume at the same time a pleasant voice will tell you your remaining battery power (e.g. "sixty percent charge"). There is no guessing if it is charged or how much charge is left. Yes the app also has a visual display on your phone but I don't always use with my phone. There is a mini-RCA (3.5 mm) jack which lets me plug in a portable turntable or an old iPod.

I looked at reviews and the UE Roll 2 was in the top three for each of the lists I saw. I went to a couple of stores and got a feel for what I liked and for sound. This won hands down for the combination of sound, portability, and the ease of attachment. I highly recommend.

It's a shame that they don't make this model anymore! I love being able to mount it virtually anywhere. I'm a James Taylor, Jimmy Buffett, Jason Mraz kinda dude...Counting Crows...that kinda thing and this SHINES!!! The volume is shocking!!! Too loud for most situations at max...so a nice 60% seems to work for me....I bought two and having one strapped to the microwave handle and one on the closet door handle across the room makes a beautiful sound. i live in southern Florida and have a pool. I leave one on my lanai table for drinking and chatting and one in my pool, floating on the surface in the included float...Makes for a great pool party...Then, if we go inside for 15 minutes for a snack, I just grab one...bring the music inside while the pool guests still have their tunes...The tone isn't a thump...though I like the bass...it's more "rich". Punchy, solid vocals with a focus on acoustic and reggae tunes....My wife likes to tweak her EQ in the app to pull out some offending upper mids...But I'm happy with the "standard" eq preset....What I love most is the small size to power ratio...I find myself always taking it with me...from washing dishes, to the shower...even popping on my passenger seat in my old 99 rodeo, cause this sounds better than the factory stereo...I think the ease of throwing it in a bag, or strapping it to a bag strap make me just wanna always have this around. The low latency and long range of this sucker makes it great for movies on the go also. I'm very glad to have scooped on of these up before they are gone for good. I assume the wonderboom is great, but the for factor and the big bungee on this roll 2 makes it tops in my book.

Looking for a waterproof bluetooth speaker, but I had also been looking for a decent external/bluetooth speaker for general use. This had been recommended by NYT (or was it New Yorker, not sure). It was a bit mysterious when I opened the box. No "quick start" or expected manual. I eventually downloaded the app on my iPhone. The USB cord was a bit difficult to insert, a difficult angel. But once I figured it out, I was very pleasantly surprised by the fidelity. I like classical music which works best with speakers that have a good middle range. So, I will be using this at my desk as well as on our boat. Pretty cool looking. I hope it can function well in the heat of the sun.

A couple things: The cross on it is actually a + and - which adjusts the volume. Push both together and she tells you the battery charge %. I tried turning it off by pushing the power button on the back, but it didn't turn off, even when I removed the usb power. Perhaps it keeps going as long as there is a bluetooth connection. In any case, the instructions on the app say it will turn off automatically after 15 minutes of inactivity. Very nice feature.

Too bad the other colors are so expensive on Amazon. But the black is just fine, as long as it doesn't absorb heat. It feels like fabric.

Pros:
Loud. Very very loud.
I love the form, the small circle is very "bringalongable" it fits in most jacket pockets!
The bunjee. At first I was very skeptical of the bunjee cord on the back. However, it is a very solid mounting point. I even use it to mount on my belt if I'm on the move!
Water proof! Strap it to the deck of a Kayak and suddenly you have your own party barge! This little guy is a tank. It really is fully water proof, mud proof, it's very drop proof. We have wood floors and it gets dropped every day. No scuffs, nicks, cracks or any change in performance!
You can pair them! I got one and my brother (who is a very proficient sound tech) imediately went to Walmart and got one right after hearing the sound quality (which for the size is also excellent). We pair them together every time we hang out and it sounds so good!

Cons:
The charging port could be easier to use.
Needs play pause skip on speaker.
Thats all!

Overview:
The affordability, size, and form factor paired with the ability to daisy chain these little guys together creates a product with excellent value. If you have the money, go for it's older brother the UE Boom. It's even better if that's possible. However if you're planning on taking this with you all the time, even if you have the money, get the Roll 2! It is plenty for any situation I've run into.
