cheap, expensive optical sunglasses

Looking for a cheap sunglasses I found this here at Subke. Ordered, delivered at short notice, so far everything well.
For the price, the spectacle OK, but it is very small and fits my 5 1/2 year old daughter almost better than me, even though I have a rather small / narrow head itself.
What negative noticed is the fact that both nose pads are not attached (made of rubber, silicone o. Ä.) Fit the frame, one of them even was unpacking in the package.
By deficient deburring both can be secure not flush on the frame / stick, so I'm curious to see how long they keep them there. Without the cushion the eyeglasses is then no longer usable. Perhaps my copy is indeed an isolated case, I can live with for the price also good so that when the glasses would have cost 20.00 or more, however, I would have complained about it. She meets my expectations - and hey, who expected a top product for the price, probably even believes in Santa Claus ... ;-)
