I picked up a Zagg HD from Best Buy this afternoon, and since I have never owned a Zagg product, it seemed like a good call to pay BB to install it perfectly. The chick who convinced me to buy it claimed that she was a professional with applying them, and proceeded to install it.
After screwing up twice, she opened the third one, and started talking about how this never happens to her. In the middle of the installation, after removing the Zagg to scrape off a few hairs with her nails, she walks away with the wet shield in her hand and starts talking on the phone for a few minutes. I am no expert, but my limited experience with other screen protectors has taught me that the more the contact side is exposed, the greater the chance that debris will cling to it.
She proceeded to do the installation while talking on the phone, and at first it seemed to be successful. But upon closer examination, there are several hairs and a few obvious "tents" of dust particles in the center, which really draw my attention away. While still on the phone, she sensed my unhappiness, and claimed that any problems I was seeing will be gone in hours, and she walked away.
12 hours since, and nothing has changed in the slightest. I hate to be picky, but it looks like I'll be heading back there in a few days to get it taken care of. With the exception of the poor installation and service, I am very pleased with the clarity of the screen, as well as the touchability. There is little to no added friction, and swipes very smoothly. Hopefully the next time I can get someone that can do it correctly.
