i had those cheap things
lasted not even 3 months, did a poorly job after that.
now bought a set of Bosch retrofits aerotwins
have the more that 4 months now and still working well
even after the sharp snow ice and winter wear they have now.
we're running a pair on our starlet demo car and weve sold quite a few to members on here and UKSC and had some glowing reports back about the quality - and they have a 12 month warranty on them.
