Not Worth it
This mount was great for about a week. After that it popped off and would not stay in place. I would not recommend buying this.

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.
