WeatherTechs Windows Deflectors 3rd GEN

I searched and really did not find any review so I guess I would give it a shot.

I bought a set (4 pieces) in black/smoked for my 4 days old 2019 Cement Double Cab.

Why I chose WeatherTech?
I don't like the idea of having any kind of external adhesive on things that are exposed to the sun. WeatherTech is well known for its design without using any adhesive on the deflectors. These WeatherTech deflectors just go straight in the window channels.

How was the installation?
Just follow the included instructions, no additional hardware needed besides those came with the box. It took me 15 mins to install all 4 pieces. It was very easy to install.

How do the deflectors function?
They work as what they were designed to do. Here in the midwest, it rains a lot and I like to roll my windows down for fresh air when I drive to work in the morning. The deflectors stop the rain from getting inside while the windows are rolled down.
Plus, they look good on the truck.

Do I have any concerns?
According to the instructions, all windows should be fully closed so the deflectors can acclimate in about 12 hours. I left all my windows up for 24 hours.
Despite the low profile design and easy installation, I think there is something not quite right.
The front windows have trouble raising up to fully close.
As they almost reach the top, the door system seems to sense some sort of obstacles, the windows are rolled down automatically. I believe this is a safety feature on the 3rd Gen Taco.
It seems like the mirrors cannot roll up 100% freely. The rear ones have no problems.

How do I close my front windows then?
Instead of holding the Up position on the windows switches, I have to do it in intervals until the mirrors go all the way up.
This definitely puts some strain on the window motors for sure.
Now, instead of rolling the front windows down, I use the rear ones instead.

Quality: 10/10
Functionality: 10/10
Fitment & Design: although they look good but I think they need to re-engineer the front pieces a little bit more 7/10

This is just a bit of info I want to share with you guys especially to those who are looking for a set of WeatherTech for their 3rd Gen Tacoma.
I hope this helps.
