Product Description
Bracketless is the new shape of wiper blade technology. As the name implies, bracketless wiper blades, also known as beam or flat blades, are designed without the metal or plastic brackets, joints or hinges of conventional wiper blades, so snow and ice have nowhere to build up. Bosch Evolution Wiper Blades feature a patented beam technology that applies more uniform wiper arm pressure along the entire length of the blade for virtually streak-free wiping performance. The exclusive, blended rubber delivers clean, quiet performance and exceptional all-weather visibility. An aerodynamic, symmetrical wind spoiler holds the blade securely to the windshield for a consistently clear wipe. Versatile double locking connector offers quick, easy, and secure installation on many popular wiper arm types (Hook, Pin, Side Lock, 16mm Narrow Top Lock, 19mm Large Top Lock, Pinch Tab) – with no additional adapters required. Replace your conventional wiper blades with Bosch Evolution and see if you don't agree that bracketless is better.

Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

Customers are mixed about the durability of the wiper blade. Some mention that they perform well, have held up pretty good, and are still in good condition, while others say that this lack of durability would be terrible for even the cheapest, no-name wipers. The bracket on this broke within a month, and some customers note that due to where they live, wiper don't last very long. The factory mechanism isn't strong enough to push it down, and all three went bad at the same time.

"...I’m not sure if it’s that the wiper itself is flimsy or the connection to the wiper arm is not precise...." Read more

Follow up: After a full day of rain today from fairly light showers to very heavy downpours these wiper blades are absolutely just great. No streaking, no squeaking, very smooth and quiet leaving behind a crystal clear windshield. Should have put them on long ago.
Horrible... just put these on two cars (both use the 26" for the driver's side [09 Toyota Sienna, 13 Toyota Camry]). Works great on the up-sweep, but horrible on the return sweep. On both cars, right in the middle of the blade (so right in the middle of your field-of-view), it only squeegees clean on the up-sweep... on the return, it leaves a gap about 2" wide of water...
I had the Bosch ICON before, and they were great. I thought I did an Amazon subscription for those 7 months ago, but apparently not... so, I'll be cancelling that subscription now. With winter about to start, I foresee replacing these shortly.
Update: 19/DEC/2017
So the first storm I had to drive in with these was horrible. This photo doesn't show just how hard it was to see through the MIDDLE of the windshield while trying to drive... I had to keep running the washer fluid to get that patch wet otherwise salty road spray was drying an opaque grey as it evaporated.
I guess I got what I paid for with these... true waste of money with this model.
I just setup a new subscription for the ICONs I liked before--just hope I can make it through the next 5-weeks waiting for them...
Update: 10/FEB/2018
One last update on these: picture from 29/JAN... yes, it was a cold morning, but you can see in the animated GIF how these just didn't work in the middle... and that was just washer-fluid to get the water spots off... there are just horrible... Got my ICONs, put them on both cars the day before a snow and ice-storm: not a problem--perfect sweep every time... even at 15ºF...
