It's been over a year I use it, no problem especially if it's topping that going to the dogs and steel grates that are fully oxidized (but good to me there are 80% of moisture is therefore not s'tonner).
Otherwise good quality sound, a bit much, unfortunately, for use DJ is not really what is most convenient (ca dpend tastes too). The advantage is that the insulation is plutt good, not too drang by the sound of the room (always use a DJ).
For the price we should not expect better I think.
