I had this great little ruggedized bluetooth speaker that had great long range connectivity and a great sound, but going on seven years, the internal battery finally gave out.
I started looking for replacements on Amazon, but everything was from the weird ass Chinese companies with funny names and all got really spotty reviews - lots of both 5 star and 1 star reviews, so you know something fishy is going on. Otherwise the well-reviewed speakers with good, loud (important to me) sound were more of the indoor style speakers and $200+. I needed another speaker that I could expose to the elements and bang around. Normally for something like a speaker, I would avoid the extra $$$ for paying for yellow, but as I have been upgrading everything to DeWalt 20v anyway, I said "What the hell?"
Anyway, After a week of use I am super impressed with this speaker. I've been finishing up my bridge rebuild, so have been keeping the speaker on my UTV parked near the bridge, and I have very clear music and bluetooth reception 30'-60' away. It also turns out having the speaker use the same batteries as the tools is really handy. If a tool goes out, instead of driving back to the shop, or having to start switching between batteries on tools when I'm using several together, I just borrow the speaker battery until I take a break. Controls are big and easy to use. Yesterday I was working in ice fog so had my insulated gloves on and I had no problem working the buttons.
About the only maybe negative thing is that it does use juice. I figured I could keep it going with one of my 2amp batteries, and it does last (I haven't timed it) maybe 6-8 hours with that (some reviews were claiming 16hrs), but I'm probably going to start keeping a 4amp battery on it. It does come with an AC cord as well though if you're using it near 110.
Otherwise, for anyone with DeWalt 20v tools looking for a "work tunes" speaker, I can highly recommend this one.
