ECOXGEAR EcoSlate Rugged and Waterproof Wireless Bluetooth Speaker (Gray) (Renewed)

review of the eco x gear eco slate waterproof rugged speaker got this at Costco it was $69.99 looked pretty good I already ordered a Logitech you sure you e boom - then I saw this one for less than half the price so go to help but to get - in any case the only thing that bothers me slightly between UE boom - and this one is the frequency range which in an instruction manual here says I could find it has a range of 125 first 18 kilohertz whereas the boom - is 90 Hertz to 20 kilohertz and then I think the ultimate boom or whatever it's called mega boom is down to like 60 Hertz so anyway it's got more bass or the other ones have more bass than this but can't complain about it on this especially for the price what does it stay here this one has more power because they think the boom - has 13 watts this is 20 watts it can charge USB devices I'm not sure I don't think the boom - can do that t
