Always had mediocre experiences with Bosch wipers and spark plugs.
The wipers work well when they're new, but don't last long.
I was using Bosch-made, then Trico-made OE refills, on OE frames. The latter were cheaper and more durable.
Winter of 2010, decided to try a pair of the Good Year beam blades they sell at Costco, since the OE frames were worn out. No complaints, and the GYs still on the car.
Hard to beat $9 for a pair when they go on sale (coupon).
