Price is $39. If you are doing service Package B or C, need to pay $22 instead of $39. Had done it twice. First experience very good. When it was time to do the second time round, it did not last very long. Don't know whether it is the workmanship or material. When that happens, it is worse than normal wipers. Each wipe will leaf the screen blur (- something like a layer of wax) for a while before it clears by itself. Soon after that, it starts to left fine water stripes with each wipe. So, if you want to try, heng heng lor.
