My sunglass holder arrived in a well packed small box via USPS mail. Teslaunch had sent me a tracking number, so I was expecting the package.
The contents were straight forward: the sunglasses holder itself, one-page of installation instructions- well written and illustrated, and 3 packs of an "adhesion promoter".

I first dry fit the glasses holder, it mounts directly to the truck right behind the OEM interior rearview mirror. I would say this install is pretty much impossible to screw up and typing the steps I took actually takes longer than the install! First, ensure the area behind the mirror is clean and then wipe down with the adhesion promoter (note: this left NO reside after drying), peel the thin red plastic off the double-sided tape and simply press/slide the holder into position. I held it tightly in place for about 20 seconds and it is well secured.

To operate push up on the middle to release and push again to close. I was able to fit both my sunglasses and my reading glasses into the storage area. The storage area is lined so I did not have to worry about scratching the glasses. When mounted it is hidden behind the mirror so no obstruction to vision and yet it remains very easy to access.

In summary, the sunglass holder is super easy to both install and use. I have to say It is a well-designed holder for your sunglasses and/or reading glasses. Recommended!
