just getting back into windows after 7 yr ish abesence....and have to say aren't micro clths brilliant, straight outta the bag, no breaking, no bits, wow. but how long do they last, it says on bag 500 washes, thats over 9 years if washed once a week, is that right. also are the micro sleeve washers any good. i went for monoon sleeves as that's what i used to use
