Customers are satisfied with the sturdiness of the wireless accessory. They mention that it has a rock solid construction, is reliable, and is pretty well bulletproof. The mount feels solid, is steady, and can withstand a lot of vibration. It is a versatile and robust mounting solution that excels in securing devices, and the clamp does a great job and never falls off.

Customers are mixed about the fit of the wireless accessory. Some mention that it fits perfectly on their 2023 Can-Am Spyder RT Limited, and is the right size for a motorcycle handlebar. However, others say that it's a bit large, and won't fit onto the roll cage bars in their track car. It's also expensive, and somewhat bulky, but very secure.

Customers like the versatility of the mount. They mention it's a great mounting system for their phone, it'll clamp to a crash bar in an airplane, and it'd be a perfect solution to creating a mount point on the center console of their new 2015 Outback. The claw is really tough and gives you multiple mounting options for various devices. Some say it'm the best alternative to a permanent mount and that it''s amazing for handlebar mounting.

2 different size jaws
4 Stars
2 different size jaws
It fits my RZR's 1.75" cage ok. 1 jaw is super small while the other fits great. The rubber non-removable insert on the "good" side should hold my phone in place without the mount slipping.My recommendation to Ram would be to manufacture the jaws in the max size and supply various inserts for the enduser to apply to their application so it gets both sides clamped onto the surface for max grip.I will update my review after the phone portion arrives and I have time to hit some rough trails.
