Excellent write up!
My factory wiper blades started streaking after about 38,000 miles, so I started looking at replacing the front wiper blades. I read all the reviews on different brands and all the posts I could find on this forum. I decided to just replace the factory inserts since the originals lasted so long and reviews for other brands were all over the place. It took about 5 minutes to replace both fronts, but could probably do it faster if it hadn't been my first time doing it. Its very easy just follow the instructions in this thread. I was amazed at how great my wipers worked after doing this and think this is definitely the best way to go with the 4runner.(I have a 2014 SR5 premium). I got the inserts on eBay for about $7 bucks each.
