IT WAS WRONG OTEM ADVERTIZEMENT WAS NOT CLEAR ENOUGH lasts a long time. Overall, nice and sturdy bench shoe rack to have. Estoy encantado con este producto Hes been an 11. I thought maybe the end was not 90? because I have read about others who corrected a track problem by trimming it on the chop saw, however this was not the case. The sound is crisp and clean, sound almost as if I was there. The noise cancelling performance on the 950N1 is certainly their weakest attribute. Didnt last long I seem to want more.
