My iPhone 5 only had a weak battery. Now it has a cracked glass panel. Suction cup is strong - so strong the glass breaks before the suction cup lets go. Apparently some of the tolerances in Apple's design occasionally add up to make a front panel assembly that refuses to let go. Phone not worth repairing at this point as it only cost $190 refurbished to begin with. A note of warning - you might want to have this done by an experienced tech - go ahead and spend the $100 or so to have someone experience replace the battery and keep the rest of your phone intact.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
