Fantastic value!
I have at least 4 pairs of these spread out all over my house (just need cheap readers).  They are very comfortable and look fairly stylish, too.  I have 2 pairs of $75 designer reading glasses and these are more comfortable!  I doubt they will last as long as the plastic is lighter weight and most likely not as durable as the designers, BUT they serve the purpose perfectly for me.
