I have tried many different wiper blades for my car. For whatever reason, it seems that even expensive blades such as the Rain-x Latitude and others even more expensive work pretty good for a while, but seem to deteriorate just as fast as cheaper blades. I have also found a lot of variability in blades, e.g. a given brand works pretty well for a time, but replacing it with the same brand and model yields a blade that streaks even when new. It has been frustrating. I decided to try these blades because they received the top rating in Consumer Reports. I have to say that they have performed as good or better than any others I have ever used, at least up to now (about one month of use). I will have to see how long they last, but my impression is very good at this point. They are more expensive than the other Consumer Reports leader, the Trico 31 series, but they are working better than the last Trico's I purchased.
