those clip ons that you slide into the hook on your windshield wiper arm suck. I'm not sure what brand is better, I usually buy the mid priced point one like Rain-X but I have had them come off before. Maybe if I paid $23 for a wiper instead of $11 they would stay on better but wipers do seem to be overpriced to me. You can't find a $7 one anymore.
Some give you that "click" sound to know its locked in, others just slide on. I try to replace mine every fall , sometimes I just go cheap and replace the drivers side, I don't care if my wife can see or not while I"m driving.
