Best mount for Gen 2 Tacoma.
Sturdy, fits good, and simple. Can’t close vent, but I expected it and it’s worth the trade-off. Highly recommended.

Worth every penny!
Excellent quality. Very easy installation. Took me less than 2 minutes. Holds phone securely. Looks very good. Easy adjustment. Very pleased. Worth every penny. Highly recommend. Update: I've been using it almost 2 months and it seems very well made. No issues. Very satisfied.

Finally a mount for my truck!
2015 Toyota Tacoma Prerunner. I've tried many different mounts - ones that stuck to the dash, stuck to the windshield, one that mounted in the cup holder in the console. They all were bad in their own way. This Offroam mount finally got it right. Easy installation - and when I say SOLID hold I mean it. No movement, no rattle, do creaking sound, etc, etc. I was very skeptical of the one-handed use getting the phone in and out but it's really a genius design. Seriously - I just got it, so can't really speak to longevity yet. Judging by the design and quality of parts, I'll say it will be the last mount I ever purchase for this truck. Pay the extra, and be happy.

Great Quality, Perfect Fit
2015 Tacoma. This fit perfectly and is solid. Last/Different one I had on another vehicle broke one of my vent dividers. That can't happen with this design. Worth the money. Would absolutely recommend.
