Fast shipping, good shipment tracking. Tools provided weren't overly useful, but I didn't plan to use them anyway. I've always had better luck with a razor blade/exacto knife, but both require you to be extremely careful, where as the tools provided offer a little more forgiveness.
The only real "complain" I can muster is that the screen replacement doesn't have the adhesive on it like the original. You must rely on the existing adhesive on the outside edge of where the screen is attached to the phone. If your original screen was shattered enough, there will be shards of glass that will make the fit and quality of the attachment to suffer. Nonetheless, this is a great alternative to sending your phone away at a much greater cost. Just take your time and be very patient. Allot an hour or so to remove a badly cracked screen.
