Recommend!!
Style: Magnetic Mount
I absolutely love this magnetic phone holder for my truck vents! The magnet is super strong, so my phone stays securely in place even on bumpy roads. Installation was a breeze—just a simple screw-in, and it fit perfectly in my truck’s vent. Highly recommend it to anyone looking for a reliable, easy-to-install car mount!

Great phone mount.
Style: Universal Mount
I went through several orders trying to find the perfect phone holder, and this is the one. I needed something universal that would fit my Toyota and securely hold my thicker phone. This mount is perfect — sturdy, easy to use, and fits great. I’ve had it since 11/2025. I highly recommend it!

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.
