Ive always wanted to get Pulse on Blu-ray but its never been released as a standalone concert Blu-ray, which is a shame (you can get it as part of the Later Years box set which is quiet pricey). Pros:-LOUD. Provides easy access to vitamin bottles. UPDATE: 3 weeks later, I have received the replacement bolt. Muy versátil. Will I purchase Chacos again though? Probably not. Says it fits standard Co2 tubing, but:-GLASS IS THE SAME SIZE as standard tubing-no nipple to make the connection-to big of an opening to fit a line adapter inMine broke when I tried to put the next size of adapter in. Cons: They are extremely springy to walk on, so use caution if purchasing for someone with walking or balance issues! Aside from the blue fabric inserts, the whole headphone looks great with the pads. Finally I dont have to deal with those common "fits 7-12" socks which go on tight and thin!
