Reviews of OEM Mercedes wiper blades

I've had the original wiper blades on my 2020 and I still have not replaced them. Exactly what is trash about them? I thought that they've been the greatest wiper blades I've ever used outside of the Mercedes wiper blades.

They're not really that expensive from the dealership, and I haven't found any that are quite as good.

w203's have this little deflector wing that only exists on the OEM blade to reduce wind noise. Others have a sticker that tells you when the blade is ready to change (goes from green to yellow to red). I think they are pretty neat, and worth the $40 you'll pay for a set at the dealership.

I buy the genuine MB wiper blade instead. The part number is 124-820-11-45, I've had mine for over 2 years and it still works great.

Maybe 6-7 years on my current Mercedes ones. Still wipe like new. Well over 100k miles. Cars are stored outside in the sun.

the OEM ones on my wife's 2016 E400 are somehow still excellent.

Placed a pretty substantial order to ECS to get things changed out: spark plugs, wires (sixteen of those f*ckers) - oil, filter, drain plug (prices on 5w40 oil locally are disgustingly expensive) - trans fluid, filter, dipstick (Anyone know why they didn't just include one on the car from the factory?) - Sunroof lube (because while I hate sunroofs and don't plan on using it, I don't want it to seize up on me) - power steering fluid (I'll do a quickie turkey baster job on whats in the reservoir) - accessory belt (Just because) - air filter (Not a fan of K&N filters) - Mercedes wiper blade (quite cheap online)
