BOSCH 3397007072 AeroTwin OE Replacement Wiper Blades: A Comprehensive Review

Fits Great. Good quality

Instructions: To replace, turn on the accessories, flick the wipers to the on position, and then turn off the the accessories. The wiper blades should come up and stay up for an easy change. If they don't, redo the steps and they should come up. Taking the old ones out is easy, but getting these in are a challenge if you haven't changed the wipers in a long time. If you compare with the old OEMs, these Bosch wipers have an extra ledge / groove that will guide the metal clip in so it requires more force and the old one. If you are consistent with your motions and just go in for the "click" everything will work out alright. Performance: They work great! I didn't even know my wipers needed replacing until I went in for a complimentary checkup at VW. They charged $45 also for a lesser quality product. These were less than $30 and took less than 3 minutes to install. When I tested them I was shocked at how good they were. All streaks were gone and the glass was so transparent that I thought there wasn't a windshield. I haven't seen my windshield looking this clean in a long time. Note: Replacing wipers is good for your windshield as sharp debris and exposure the sun will make the wipers hard and scratch the windshield. For best results, use the wipers when the windshield is wet and clean under the wipers monthly to make sure no debris was lodged under the blade which will cause damage to your $300-$500 windshield. Thoughts: Bosch is a quality product and brand. They are OEM for many German makes so rest assured, these will do the job and are probably the best replacements you can get. Bosch was chosen by the manufacturers who know their cars best. It's best not to second guess their expertise of 1000s of engineers. Most decisions about your car should not be trusted to the average person and their neighborhood guy at Autozone. I've heard of a lot of people using aftermarket parts which affect other parts. Even though a windshield wiper isn't the most critical part, the same concept is true in terms of the longevity of the wiper and quality of performance. I have kept my car stock to the nuts and bolts and it has never broken down on me. Treat it like a lady and it will treat you and your wallet well.

I am a DIY kind of person and looked up compatible wipers with my car. These were a cinch to install (5 minutes!) and work wonderfully. I cannot speak to their longevity as it's only been a week or so with them, but I've used them in the rain-- there is zero squeaking, and they wipe very cleanly. They appear to be very well-constructed and sturdy. I am pleased with the price and my experience thus far. Would recommend.

Wiper does not fit exactly for 2009 BMW 328i sedan. The hinges are little bigger than genuine BMW wipers. The caps holds wiper blade and works perfectly. It is value for money. But I would choose genuine BMW wipers over these wiper blades.

The pivot point of the wiper blade is not exactly in the middle. As a result, when you install this you have to be aware of the orientation. "Test fit" the blade first, to make sure you've got it the right way. The wiper holder is purely ABS plastic and it's a friction fit, so you have to pull hard to get the old wiper off (I found nudging it at different angles helped). Installation requires firm pressure to get it to snap in all the way. The wiper cover doesn't sit 100% flush over the wiper, but it's barely noticeable. The quality of the rubber blade is excellent. NOTE: If you got this blade recommended for your car and the frame isn't compatible, there is an option: remove the rubber blade and swap in place on your existing frame. An aged frame will work perfectly fine, as long as the blade pivots aren't stiff. And you can loosen them up with a little WD-40. A tip on blade longevity: Every few weeks or whenever you wash your car, take a moist paper towel and drag it across the blade (pinch and slide) to remove any debris stuck to it. Avoid using your rear wiper if the window is completely dry (the worst thing is for the rubber to drag across dry dirt, which will cause micro-scoring). About twice a year, take off the blade and bring it inside to wash with dish washing soap, to get rid of any micro debris that is stubbornly stuck. Rub your fingers over the blade and feel for any "nubs" of debris that didn't come off. When you do this, your blade will last a very long time. Mine typically go about 4 to 5 years before needing replacement.

After searching locally and getting the wrong wiper, I ordered the Bosch unit that Audi put on at the factory. Shipping was quick, by Alaskan standards, and the unit snapped right into place. Solid build as you would expect from Bosch!

Great product as advertised. Fits perfect
