I bought my 4th pair of these shoes July 2018 because I was such a big fan. fml. Man läuft wie auf Moos! I purchased it for two 9-year old birthdays. Wish the company would provide a longer bolt. Now, even on the highest setting, I can still hear fairly amount of the surrounding noise. Los Bose son los únicos de la lista que aprietan y tienen el giro al contrario que el resto. Why isnt this five stars from me?Because the description says HARD shell, and I can definitely compress the case with enough pressure applied. Now for the product itself great build and easy to put together did it myself in about 30 minutes. We painted and polyd these and used them to hold a sash above the master bed.
