I bought these because all of the other rain guards that I saw that were not OEM were not as great looking as I wanted.
I looked at maybe 6-7 different models for my rain guards and did one was the one that I liked the most. I wanted something that was aesthetically pleasing but also had great function. These don't stick out as much as I want them to but compared to the others options available these seem to hold up just as well as the competition.
As far as the look goes this is one of the better looking ones that I saw, the installation was fairly simple and it does come with some adhesive support to strengthen the bond. I skipped using that step because I didnt want to risk running some off that stuff on my paint or trim and just installed the product carefully. It has been installed for 2 days now and I did drive my car a fair bit and no issues observed so far. My car as been out in the heat and so far I see no signs of them wearing out from the sun.
As far as fitment and obstructions, I noticed none. They fit perfect, you just have to make sure you measure it correctly and want to get it the first time. I removed just a bit of the plastic on the adhesive and as I was holding it in place peel off the plastic trim on the adhesive while the rain guard was on the trim piece by the window. Installation was very easy and I did the entire car taking my time in about 5 minutes.
There was no obstruction opening and closing the windows. I tested every single window and made sure it was able to close and open. I'm able to open the window maybe 10% of the way before they are no longer covered by the rain guards. Which is perfect because I just need to crack the window slightly when its raining and these will do a good job preventing rain from getting in.
