You'll get exactly what you ordered. The staff is knowledgable. Clearly English isn't their first language, and the product arrived a little late. But it was EXACTLY what we asked for.

I needed the sfp cage quickly. Did not want to spend a whole lot of time trying to muddle through a complicated website looking for what I wanted. LINK-PP did just that. Up to this point I did not have a favorite site for my needs. Now I do.
