Review on Boao 4-Pack Car Sun Visor Glasses Holders, Sunglasses Holder Clip Hanger Eyeglasses Mount, 180 Degree Rotational Double-Ends Clip Car Glasses Holder (Gold) by Robert Wells

The gripping piece that is supposed to stick to my car's sun visor doesn't have a strong grip. I clipped/placed it on the window shade and after returning from the store I got in the car to drive, the sunglasses handle falling into my lap. I put it back on the visor and noticed that it became "loosened". I don't understand how or why. I'm using it for the first time so it shouldn't lose its grip. I bought the complete package. I'm not sure I need them when my sunglasses fall on the car seat with the handle. Not expedient. Updated** The top part you click to open the handle is broken. The product is very cheap
