I don't forget to cancel all that often, it's not like every time I use them I forget to turn them off again but you only have to do it once at the wrong time/place to get wiped out. A £45 outlay is soon forgotten about to be honest but if it saves my skin in 6 months time, without getting on my wick every time I use my indicators in the meantime, I think it's money well spent but maybe that's just me. It's quite amusing how upset some folks get about how other people spend their own money.
