Quick response and was extremely helpful. The scope itself very well made, and very easy to use and installed. It actually works better, because you can hang from the midpoint of the shelf, conserving hang space. It looks like and air bike, with the fancy wheel but, it is just a normal bike. This is very flattering and I received compliments all night long. This is a superb radio. Purtroppo si sono rivelate troppo grandi per la mia testa (pure a regolazione minima i padiglioni sono troppo bassi e si appoggiano di peso alle orecchie, piegandomele in modo alquanto fastidioso) e non aderiscono bene (se chino la testa mi cadono, letteralmente). For me personally, they tilt outwards so they dont even create a solid seal around your ears. I could breathe just fine. I find that it doesnt have enough memory and Im constantly fighting to keep the wires around my ear.
