I was so upset when I cracked my screen on my HP dv7-7121 nr. I called around locally to see about getting it fixed and was quoted $325.00. I did not want to spend that much on a new screen. After finding a video explaining how to change out screen I decided to try and change it myself. I am not that computer savvy and was actually scared to start taking my computer apart not wanting to damage it any more. The installation was a lot easier then I thought. Really anyone can change this screen out. I'm so glad I could save $225.00 by doing it myself. Only took 15min to change out and 10 of those min were because the frame around the screen has adhesive on it and I took my time so I would not crack it. New screen worked great and picture looks great.Received and installed yesterday. Packaging was perfect (small but strong box with the screen suspended in the middle with solid bubble wrap). Installation took about 30 minutes, no issues but the three connectors can be frail. After install, everything was working as expected.great price and quality
