Best vent mounting solution for tacoma
Style: Magnetic Charger Mount
This is a must have for Tacoma owners. It's a secure lock into the vent frame and does not affect your ability to open and close vent. Installation takes a minute.

Misleading description
Style: Magnetic Mount
Misleading. It does affect the vent. You cannot turn the vent at all and it cannot be closed 100%. About 95% closed. Seems very well built and sturdy however, I wish I knew that you cannot turn the vent… Not sure how I feel about that, I may return it.

Happy after aggravating install!
Style: Magnetic Mount, Style: Magnetic Mount
Works now that I finally got it to hold. Otherwise would have given it 5 stars. The air vent ‘lip’ on my 2018 Tacoma is so short so not much for this to clamp on to. This was hard to install. Instructions didn’t have anything about putting the parts together and extra cushion pieces. I watched the video and it was like mine once I got it to hold. I tried with one layer then added a layer then removed added layer and then finally got it to hold! Maybe 10 tries! Now that it’s holding it’s perfect! I left it unscrewed just a little tiny bit so can move the phone view around a little. Happy now!
Build quality:
It seems to be pretty strong and will last my truck’s lifetime.
Phone mount:
Like that it is strong magnet holder and not bulky
Ease of installation:
Not easy. Kept not staying attached then finally just got it. I don’t know magic trick but was just about to give up then it caught the small lip and held tight. Ever other attempt kept popping off as I tightened it down.
Value for money:
I think at $39.99 was a little high but hopefully last one I ever buy.

Solid iPhone Holder
Style: Magnetic Mount
I’ve been searching for a phone holder that doesn’t take up one of the drink holders and actually works well. I had been eyeing a vent mounted holder but was hesitant until I found this one. It had good reviews and was designed to work with my Tacoma. I decided to try it and was pleasantly surprised. It was easy to assemble, fit perfectly, secured nicely, and held my phone in place even in bumpy conditions. The vent location puts it in a good alignment with my vision which is especially helpful when I’m using my navigation app. If you’ve been looking for a decent, reasonably priced, well-built iPhone holder, this is an excellent choice!
