I installed these blades on the front of my 2002 Toyota Sienna.  The blades that I owned previously were the traditional skeleton-frame blades with a 6-point contact system on the windshield.  These traditional blades work fine, but they do tend to get clogged with snow and ice, and the single points of pressure don't always apply pressure evenly on the windshield.  The ACDelco Clear Vision are a flexible blade that applies even pressure along the windshield with no skeleton behind them.  My first experience with this type of blade was the Rain-X Latitude which worked quite well, but fell apart rather quickly.Enter the ACDelco Clear Vision Wiper Blade which is very similar to the Rain-X Latitude.  I received the 24" and 18" blades to fit my car.  The first thing I noticed is that the blades ship in hard plastic cases that open very easily.  No scissors or razor blade required - the box just pops open.  Inside the box is a huge array of attachment mechanics for various wiper blade styles.  There are Top Lock Pinch Tab, Top Lock Push Button, Side Lock, Hook Lock, and Pin Side.  For the Toyota Sienna, the hook lock set was the right one.  You just "snap" the hook lock adapter into the blade and then snap the hook into the adapter.  The instructional photos are rather small - it would be nice if the adapters were more clearly labeled (or the instructional pictures bigger), but I figured it out.Another innovation is a circle that changes color when exposed to UV that acts as a "timer" for when to change the blades.  You remove a protective cover of tape and the black circle will eventually turn yellow.  I haven't had them long enough to evaluate this feature, but it's a great idea.  I didn't realize how poor my old wipers were performing until I put on new ones, and frankly, I can't remember when I changed them last.  A physical indicator is a nice feature, both for helping ACDelco to sell more blades and for me to know when I should be looking to replace the blades.The blades clean off regular rain just fine - no streaking and very clean.  The flexible design means snow and ice won't build up on them.  My last experience with frameless blades (Rain-X latitude) showed them to be less durable than the traditional type, so I'm hoping the ACDelco Clear Vision hold up better.  Time will tell - I'll likely update this review in 6 months with my experience.  For now, I'm quite happy with the replacement and can recommend them.
