lensrentals.com had several reliability reports of which lenses were
the most trouble, citing sigma as being the worst to the point where
they refused to carry sigma lenses when another maker had a similar
lens.

some simga lenses were dead on arrival from sigma, never having been
rented to anyone, and when lensrentals contacted sigma for repairs,
sigma said user damage. 

sigma ultimately forced lensrentals to take most of those reports down.

some older sigma lenses were held together with tape:

  On another Sigma lens I had, the front part came loose, and the lens
  wouldn't focus. I discovered that it was attached not by screws, but
  by some sort of double-sided tape!
