My wife dropped her 5c onto an edge from about 2 inches above ground: most of the LCD panel cracked into small pieces!
Ordered the replacement from Amazon: http://www.amazon.fr/dp/B016S1ZM8E which retails for about 38€ here in France. Full featured with all needed tools incl. suction cup (unusable as I tapped the screen to avoid the tiny bits and pieces of glass falling off) and another lever with sticky tape to lift the screen.
All went well even if it does seem a bit risky to lift such thin plastic connectors as the one for the proximity sensor for ex, nothing ripped or broke.
Only part not fitting 100% is the original back metal panel into the screen, had to apply some pressure to get this in.
Tested screen functionality before closing the phone, all fine, retested now with everything in place: seems to work ok and looks like new ;)
All together including a smoke break about 3/4 of an hour.
Once you have the screen lifted and are starting to remove the various cables, I would advise, if you're doing this by yourself, to leave the suction cup on the screen and tape this to the support you lean the screen on so nothing slips unexpectedly. Or get someone to securely hold it - better be seated, it takes a while...
Also, use a clean support like the top of a cardboard box, big enough, to lay out the various parts you remove the have them in the right order and placement for reassembly.
