Everyone else uses screw-on type magnets.
The genius at Sigma decided to use a design that either seizes on bladed spokes as used in Mavic wheels and other popular spokes like Sapim CX-Ray and makes it very difficult to take off, or doesn't fit on thin, round ones, like DT Revolutions, which makes the magnet move around.
I've never had any of the issues your describing with the rubber band or magnet and I'm using those exact DT revolution spokes. Interference even though there coded and loosing signal is a big problem. Lost 3 km on my ride today and cadence was all over the place.
I'm going back to wired, the 5 year old Cat eye Astrale 8 on a older bike has the original batery. The sigma 1606L wireless I've gone through 7 in just over 2 years.
