Now that the rainy season is really upon us, do you guys replace your old wiper blades or just use the old ones no matter how old until they start streaking?

My experience kasi, I replace them every year when the wet season is in full swing. I just buy the less expensive brands since I mean to replace them next year again. Consumable items, so to speak.

Why risk diminished visibility for a few hundred pesos every year?

Thoughts?
