The thin casings are what I like most about these pilots, however they may not be the ideal glasses for those of us who have a cumbersome nature. The thin casings can twist or even break in case youre not cautious with them, and they are a costly speculation to need to twist once again into shape constantly.
In the event that you have long hair, youd need to live with another pilot issue also. The nose watchmen can get on a cluster of hair in the event that you set them on your head, and the hair once in a while remains in them(and after that tears out) when you attempt to return them on. Ive had this happen with different glasses, and OUCH.
That being said, in the event that you truly need a couple of these(or any great pilot really) simply recollect not to pop them on your head!
