Query: Avoid, product design FAIL

For some reason the folks at startech decided to go for style over substance; why they would do that for an item that screws into the back of your case I don't know.Anyway, these things look really nice when you take them out of the package. they're very shiny. upon closer inspection you notice that the metal is ridiculously thin; like soda can thin. because they're so thin, they don't sit flush like they're supposed to; they twist one way or the other; it's impossible to get them to fit properly.I bought these to add a little structural integrity to a cheap case, and for that purpose they completely fail. they might work better in some other type of case. I also feel they're overpriced, but maybe they're something of a specialty item
