Absolute garbage. The plastic pegs that hold them on don’t hold them on. Lost on in a storm on a major highway, now I have a scratched windshield. Worst crap ever, buy some Rain-x ones.
Still have one from the last Woot rolling around in my trunk, because even though the configurator said it fit my vehicle ('07 S60R), the clip was incompatible. Can’t comment on its construction or utility, as I can’t mount the stupid thing.
Actually Bosch makes very good quality blades. The ones listed here are for J-hook style wiper arms only. Perhaps improper installation led to the loss of your wiper blade. If they are not properly latched they will come off and sometimes it is hard to tell if they are latched.
