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.

The fit is perfect and is a sold mounting system
Custom fit for 2022 Tacoma, fit exactly. Very sturdy mount and took seconds to install. All metal with the exception of a adjustment knob. Quality hardware. More expensive than a lot of mounts but most are cheap plastic and are not nearly as solid and sturdy as the Offroam.

FINALLY a decent phone mount!!!
I’ve tried about 5 different phone mounts in my 2018 Tacoma and ended up throwing them all away. They’re either too bulky, too weak to hold the phone, awkward or just won’t stay in place. I won’t install a holder that requires adhesive or screws into the dash (or anywhere) in my truck. This holder is the answer. Fits perfectly, doesn’t damage your vehicle. Holds the phone really solidly. This is a very sturdy mount.
It’s a bit pricy in comparison to other phone mounts out there. IMO, it’s worth every penny. Materials are far superior to your typical mount, which I’m sure drives up the manufacturing costs. Again, worth every penny. Also, it’s a small business based in the US. Love supporting our small businesses.
GREAT MOUNT!!!
