When I opened the box only one speaker had water in it. So I found these directions for filling it. Both speakers had broken pieces in them. When I opened the back of the empty one, there wasn't a plug. Instead, there was a big thick layer of apoxy or something. When I finally got enough of the glue/apoxy stuff off, I put the water in and glued it back closed. Then, while trying to get it back together, three wires broke lose. My husband said he would try to sodder the wires back in place when he got a chance but I'm not optimistic it will work. Luckily, I didn't pay anything for the piece of crap. It was given to me. My husband said if he couldn't fix it, he would buy me another one......don't think I really want to chance money on buying another one though.
