You can buy the genuine one here. Why weathertech?

$158???? really? these are plastic tape on jobs not gold. :o Ebay has them for $28. https://www.ebay.com/itm/Visors-Wind-De ... 4405!US!-1

My question is do they prevent the aweful buffeting?

in answer to the person who said that it is the low drag (presumably meant aerodynamics) that causes the buffeting sorry, but that is totally incorrect. buffeting is changing pressure at a low frequency caused by turbulence. the turbulence is related to the size of the window opening the lack of straight through escape and the convex back window surface. to verify the window size open the window at different amounts and notice the intensity and frequency change. to verify strait through escape open the rear window diagonally from the front one you have open. vary the amout till the buffeting is almost gone. to verify the rear window shape drive with the rear hatch open.

Nissan and other car companies could fix this buffeting with openable vents at the rearmost part of the cabin.

"I wonder what effect they have on aerodynamic drag. Suddenly your waving these arms on the side of the car all the time, might be negative on range."

absolutely no impact on range. the aerodynamics of these are negligable at even high freeway speeds. perhaps at mach 1 you may have an issue but they would tear off before that.

There is no mass market for that type of product unless you can find an existing one that fits..

Noticed this old thread about the wind deflectors etc. We live in Florida where evenings are awesome for driving through the neighborhood real slow with the windows down. The pedestrian warning sound the leaf makes ruins the open window drive for us. Wish Nissan could do a software update to turn it off after 8 mph rather than the appx 20 mph.

Next Nissan suggestion would be to enhance Leafs software to regen all the way to complete stop. Now that would be nice. :)

That's essentially what ePedal does, with a little help from the friction brakes.

Yep, ePedal is nice. We use the creep mode for close parking. Just seems to give us finer parking control by hovering over the brakes with the left foot and accelerating with the right foot. We do this to get over the hump in the garage entrance and stop the sudden acceleration after going over thereby avoiding unwanted ventilation in our garage back wall. ;)

I spent most of the night reading pros and cons of 0 mph regen. It was overwhelming. Lots of comparisons from many manufacturers, Tesla, Leaf, Bolt, etc. Good reads.

So, I really don't mind to look of wind deflectors and I use them most of the year (Alabama) when I park at work to let the heat escape. I originally put a set of WellVisor deflectors ($49) on and used them the past two years. They looked OK and worked well, but they had little plastic pin holders that kept popping off. WellVisor customer service sent me additional ones, but everytime I washed the car, somehow I always managed to snag one and have it pop off. Finally the past few months the tape started giving way and they would vibrate when going down the road.

Anyway, I was looking for replacements and ordered a set off of Amazon (different company) for about $60. But before I put them on I went ahead and checked japanparts.com for the official Nissan version. Although they were quite expensive ($160 plus shipping from Japan) I went ahead and ordered them (it was my birthday present to myself).

I just got finished removing the old WellVisors and installing the new Nissan one (took about two weeks to receive from Japan, but had good tracking). THEY ARE FANTASTIC! They are much lower profile then the others, they hug the window much tighter and are very clearly much higher quality. Expensive, Yes, but I think they will last the life of the car and really look good. Nissan did a great job with these, it is a shame they are not available from U.S. dealers.
