We test software and mobile apps across several platforms in our downtown office, two blocks south. When the inevitable cracked screens happen, this is our go-to place. I've also used them for soldering on a Mac Mini and battery replacements on a couple of other devices. They are prompt, courteous, honest and do good quality work; I've never had a problem with any repair, but have no doubt they would make things right, if and when. They just turned around a screen replacement this morning on my iPhone - took about 45 minutes and it's good as new. They've got a pretty good selection of cables, accessories and cases on hand. They (currently) offer $10 off of any repair (walk-in), plus 10% off to students and government agencies and workers. There are (slightly) cheaper places in the strip-malls closer to home, but if you're downtown and need a repair, they're convenient (exterior storefront on the east side of the San Carlos) and reliable.
