I believe this clip is made very well and will last a long time, but the spring of the clip is so stiff I feel like I'm might damage my glasses trying to get them in place. Getting them back out is also a bit of a challenge. I have been used to a clip that I could operate with one hand. Maybe it will loosen up over time.
Only sunglass holder that I have found that actually works and lasts a long time
Works very good have one in all my vehicles well built at a fair price
