However, after two Sunday uses the mic boom on the Master unit wouldnt stay in the up position which turns off the mic. Also, they give extra pieces, and every tool needed is inside. The slippers may feel tight at first, but they do stretch to fit true to size. i love these beads. And they dry out quickly too. I have a very old house and the floors arent level, but considering that, it seems pretty solid. Just as good as ones from the dealer, with a better price tag and super easy to install. Very flimsy. Do not buy these slippers. and they?re not terribly big, so they?ll be ok.
