Fantastic Mount especially on rough Roads
Robust and discretely positioned mount. This mount is the real deal. It is by far the highest quality most stable mount that I've ever had in my Tacoma pickup. I also really like that it's positioned closer to the steering wheel in instead of in the windshield, making it easier to view. Very highly recommended!!

Perfecto Product!!
I rarely write reviews, however on this product I need too. This clearly is a pricey phone mount, but after reading so many reviews I went for it & purchased. After opening, I immediately could see & feel the quality of material used. Installation was surprisingly easy & quick to my Tacoma. The mount is very firm, sturdy, very adjustable, perfectly designed product. For as costly as this was, I have absolutely no regrets! Totally can recommend this product to anyone with a Tacoma within the stated production years. So as so many others have said accurately in reviews, I am beyond satisfied even with the cost in mind.

Perfect fit for my 2018 sr5 Tacoma. Great quality!
Extremely well made. Doesn't rattle or slide off. Holds the phone tightly. Finally found a phone mount that works great for my Tacoma (2018 sr5). I highly recommend this product.

5 Stars with 1 Call-Out….
SOLID built like a tank! Really like the all-metal design. No vibration on the road and minimal if any off road, extremely stable. 360 adjustability = endless options on positioning your phone. Overall a good buy considering fit, form and functionality as compared to the less expensive composite holders that shake move and rattle (Drives me nuts). The ONLY negative…. I have a pro max iphone with a case and there’s no way one-handed operation works to insert and remove the phone into the holder. You can use one hand to adjust the angle and positioning but not otherwise. An OFI for OffRoam, incorporate a tension adjustment into the design for ease of insertion and removal of the phone (without breaking the bank). Taking all things into consideration the pros far outweigh the cons! Best unit out there for Gen 3 Tacoma owners.
