My tablet had just stopped working. I tried to diagnose it myself to no avail. The tech here was able to check it out in less than an hour (at no charge, nonetheless). He identified the problem as a bad motherboard, and advised me that it wouldn't be cost effective to have him fix it. Many places might have run me through the gauntlet, suggesting expensive fixes or charging a huge diagnosis fee. I really appreciate their speed, professionalism, and integrity, and will definitely go back if I encounter a similar problem in the future.
