Summary: When using the Aux in (with rubber flap unavoidably open) the Aux button rattles terribly (same sound as having a torn speaker) with even low volume or bass. If you're only going to use this with Blue Tooth (and can keep that rubber flap closed over the Aux button), the Aux button probably would not rattle. I cannot comment on any other aspect of the device (charging time, holding a charge, etc.) as I had this thing packed up and ready to return within minutes- awful.
Summary: I purchased one of these a Brookstone before RAGBRAI in July to use as both a speaker and to charge my phone while cycling. - It's not loud enough for another bicycle to hear. - It's bulky, and the mount points make the speaker upside down. - The solar charging is too slow to be truly useful. - The speaker now refuses to turn on. - It seems to lose charge over a week or so when turned off. I wish I could return it for a refund. I wouldn't recommend it for anyone.
Summary: The quality on the Eton was nice but the inferior sound was annoying, Buzzing with heavy bass songs and muddy treble. Sent back and bought the Bose mini speaker. Night and day difference in sound.
Summary: To me, this speaker was meant for outdoor durability, camping, hiking, and outdoor activity. The speaker worked OK with bluetooth in the house, but as soon as I took it outside to throw the frisbee around and take it for a hike, the speaker performed horribly (skipping to the point where silence is bettter).
Summary: I purchased Eton Rugged Rukus on May 15, 2013, from Amazon. com and have been unable to charge Eton Rugged Rukus under Solar Mode. The LED indicator shows only one RED light (the left most of the 4 LEDs) on the display. And that LED was NOT blinking, contrary to their manual's instructions. The Eton hotline was contacted and I received an email from the company representative. Fortunately, I was able to return it to Amazon for a full refund.
Summary: Bought this for the deck, for outdoor listening. When ten feet away outside, you can barely make out what song is playing. This is with this volume all the the way up on my iPad and the speaker. The iPad4 I am using, and all my iPods, blast from headphones. I wanted to be headphone free when in the hot tub or doing dirty work like sweeping the driveway, etc.. What gives? This is with the best fully charged AA batteries money can buy.
Summary: do not buy this stereo! i used this for the first time in primo weather conditions, bright sun, few clouds. it cannot charge phone while charging the internal battery it cannot charge the internal battery and play. it will kill the battery. even without the iphone plugged in! it cannot play without bluetooth! it cannot charge a completely dead iphone, it does not recognize something is there unless it is powered on.
