Very good communication and customer service Ordered 320 GB Seagate hard drive. Shipping and delivery was quick. Drive was noisy and not working properly. Seagate diagnostic tools confirmed that drive is faulty. Emailed 3bTech on Saturday. Received response early in the morning on Monday that they will re-ship another, tested, drive. They didn't even want broken drive back to save me on shipping costs. Received replacement drive next Saturday. Drive works very well. I'm impressed with their response time and customer service. I've purchased couple of hard drives from them in the past year or so and never had problem with them. Thank you Jan
