My Bosch are probably about 4 years old. Have not started to streak.
Owner reviews for wiper blades
Bosch Icon. Going on 5 yrs and just starting to streak a little. Truck outside 24/7 hot sun but only a few weeks of cold to a few days of freezing (South Texas).
Best I have used.
Silicone is the material. PIAA was the starter/most popular, SilBlade is a cheaper option. My PIAAs lasted me 10 years on first set. Got inserts and they are like 7ish years old now. Plus the silicone coats your windshield and give you a light RainXish coating.
PIAA Silicone blades. They last much longer than any others I've ever used.
A little more obscure than Bosch, but I've found them to be superior and last longer. PIAA Si-Tech. Lasts 5-7 years for me with no streaking.
I grudged paying for Bosch wiper blades through my MOT repairs until I actually used them. Won't buy anything else now.
Bosch Aerotwins with Rain X fluid. I am usually sceptical about such expensive alternatives to pretty much anything from Tesco, but with a new set of blades it's brilliant stuff.
Bosch have been generally good for me, I managed 4 years on one set of front wipers on my panda and they were still good when I sold it
I currently have RainX Latitude wipers on mine, and they seem to be about due for replacement, bit I feel like they didn't perform well when they were new.
Tricos just touched the windshield frame at the bottom with a loud click every wipe
