The glue wasn't holding on the replacement screen/digitizer on my iPad mini. I brought it back for warranty repair. He remembered me and, without any questions told me he'd have it fixed in half an hour. When I went back to pick my iPad mini up, he let me know that he actually placed a brand new screen and digitizer to make sure that the glue would properly adhere.
I'll be brining anything electronic to this guy for repairs and, recommend this place to anyone!
