The keyboard itself is amazing and Logitech did a great job with this one. I bought this so I could attach a newly purchased carbon MTB to my Thule bike carrier. So I went to the hardware store for a piece of copper piping (pvc or other light material fine, too) the length I need, adhered it to the original rod end-pieces and - voila! Theyre a regular part of the gear in the family boat. No distortion on this thing & no DSP as far as I can tell that lowers sound level at max volume. The knobs and bolts that hold it to the roof rack are so large there is not enough clearance between the rack and the roof. Ich habe jetzt Badelatschen einer anderen bekannten Marke und bin deutlich zufriedenen damit. Downward????does. They really need to add better depth and width to this shoe because there was no way those were sizes 8 and 9. This research led me to the Sony MDR-V6 headphones.
