Ray Ban 3217 - fragile?

[Skedenj]

Hello guys,
please help me with this one.

I'll probably buy Ray Ban's 3217 sunglasses, but i've been warned that they are likely to break since they're rimless. Does this frame on upper side give any support and prevents them from breaking so easely or it's the same and they're really fragile?

Is it also true that you have to tighten the bolts all the time?? :S

These're the pictures of them:

Thanks very much for your help!

I have always stayed away from rimless glasses. I mean fishing wire is meant to reel fish not support sunglasses. That is just IMO though. I stick with the conventional frames... Personally, I prefer Oakley, Armani, and the more contemporary Raybans depending on my mood.
