After continued & extended use of the Astro C40 TR Controller, the analog thumb-sticks have become faulty--squeaking loudly and making a lot of noise whenever used. In addition to keeping me safe by keeping my hands on the wheel, this keeps my phone safe by keeping it out of harms way where it belongs. I bought these from Amazon warehouse deals for about half the RRP. 5 mm. Further this carrier is fairly bulky and awkward when not mounted to the vehicle. Zero stars but had to mark one to post. awesome all I can say! Thinking about buying one for my mom. Not comfortable fitting, I ordered c12 size and I received items big size Plus, the comfort factor gives you permission to wear them wherever necessary.
