I'm a woman the blade was easy to put on to the old windshield wiper. It comes with two different settings for two different sizes again it's just amount of pushing it in and the wiper was on fairly a five minute job. Good quality great price.

These are better than the more expensive pair. Rainx is a very good product, they last a long time. They hug the glass ans leave no streaks. A great man from the tire change lane saw me struggling in the rain to put them on. He left his bay and came out to do it. I was 4th in the oil change lane. I think his name was Leo, the gal taking info from other cars knew his name but I forgot. The kicker was he refused twice to take a tip; that's service. A local tire chain wanted 60 dollars for the same thing.
I always use these wipers on my foreign cars. They are of great quality and are reasonably priced. They are very easy to install. Would definitely buy again.
A little pricy, but the day after putting them on, these wipers cleared the windshield with no streaks while driving through rain. Haven't had time to see how long they last, but so far so good.
Rain X Expert Fit Wipers are the Best, reasonably priced, and easy to install wiper blade in the market. I use them on all my vehicles, and have for many, many years.
I've had such a hard time finding wipers that EASILY can be installed on my 2016 Cruze LS *without* needing some stupid adapter(that for whatever reason wasn't sold with any of the wipers I've tried before…). These were literally ready for installation right out of the package! Popped off my old wipers and had these new ones installed within a minute total!
The manufacturer has changed the fittings to fit several different adapters to the wiper. Not so easy to replace as once was. We've purchased before and it was a perfect fit.
blades are great..itwas the shipping that was the problem shipped separately and didnt get one absolutely ridiculous rainx is great walmart not so much
I bought three wiper blades windshield wiper blades for my car, I put in the make model year and trim package of my car and you picked the windshield wipers blades for me. When they got there and none of them fit. So I took the car to Walmart and had them to try to put them on and they told me they were the wrong ones. So they sold me three more and none of them fit either the associates couldn't get those on. So I just got a refund and went to Walmart I mean Toyota dealership and bought them there. It was a terrible experience. You really need to work on that
The wiper inside the package was not the wiper that should have been there. It was some other random brand that have been shoved into the rain-x package, and there were no connectors to use it if I had wanted to. I ordered two different sizes of the same wiper, this was not the same.
