TLDR:Just buy new wiper blades, screw the wiper inserts. They are not worth it. Seriously.
The Story: Girlfriend's new (well, CPO) 2024 Camry needed new wipers. I look online and everyone seems to be like "get the inserts, bro! Keep the original blades!"
So I look on Amazon. Ok, they are cheaper and "does it fit" box says they'll fit. Youtube videos make it look like the inserts slide right out and in. 5 minutes... yeah, right...
They get here, I pull off the old blades but the inserts have a notch. Stupid things took forever with a screwdriver to get them to slide past the notch. Finally out, I go to put in the new inserts, holding the metal tabs. They don't slide in...why? They're too big. Turns out the ones I got were the generic 8mm inserts, this thing needs 6mm inserts. So, the next day I bring the inserts to ups store and return them.
I go back online and think "I'll go to a Toyota dealer and get the right ones guaranteed, easy peazy"...Got a good price on them at a dealership down south and had them shipped to me.
A couple days later, they got here, yesterday. Struggle struggle struggle, get the old ones out. Try the inserts. The driver one gets on. But then there's the passenger one.
STILL TOO BIG!
I think "ok, I'll try the one I got in." Still 2 big streaks...oh god...
At this point I'm completely fed up. I jump in the car, drive 15 minutes to Autozone and buy a set of Duralast Flex. Check with both the counter and Gemini that they'll fit. They both say "Yes".
So I go outside, pop off the old blades, pull out the new ones. Don't need any of the attachments, the Camry bracket is the default. OK. Pop them on. Do a window wash. Perfectly clear. Total time to change those? Literally 5 minutes. And a minute or two of that was the blades were a little hard to get out of their plastic shells.
So, just passing this along. If you think doing the inserts will help you save a buck. Understand you're playing Russian Roulette. Or just go buy a decent pair of aftermarket blades and save yourself days of frustration over stupid wiper blades.
Thanks for listening to my rant.
