Easy installation. Very sturdy which was my concern when I first looked at this product. I wanted my phone to the right of my steering wheel so I finally went with this version and am glad I did. I do recommend a test fit prior to removing the film covering the pads simply so you realize exactly where to squeeze the clip so it fits smoothly into place and is recessed into the air vent prior to the sticky pad touching the vent. That is what I did and the installation was easy. The only thing I would recommend is that if your hand strength isn't that great then have someone on standby who can do it for you. With that said, it wasn't that hard to do. As I recall, the top is just put into place and then you squeeze/squish the bottom clip up towards the top clip and guide into the air vent and release once the edge of the recessed clip with the glue pad is in place. I then reached around the back of the clip and pushed on the upper and lower pads out of paranoia but I don't think it was necessary. All of the instructions are in the bag with the clip. I did take a brush to my air vent where the pads will sit prior to installation of the clip. I then installed my phone holder (iPhone 7 plus with larger case) and it has held the phone perfectly. I would definitely recommend this product if you're searching for a phone holder that will work with the crazy curves of a Toyota Sienna.
