Do be sure to follow instructions for laundering, never use bleach. My microphone is ,however, within four feet. One complaint is the back that cups your heel is a little big, but it really isnt a big deal! I do own another pair of sketcher sandals and had them for 6 yrs and they?re in great condition. I didnt want it to be so tight that it was hard to put on and taken off. Even if the very heavily accented voice did confuse momentarily. Its not a big deal, and I know if they clamped more, theyd be less comfortable, but engineering could work this problem out for a better compromise. Timing is 9-10-9-26. The cable worked fine for about 5 months then shorted out. As for the trigger mod.
