(1 star) Fails constantly

By: nintenjoe
This technology has been used in my place of work where there are daily cases of it failing to connect my computer to devices and the network. The device will be plugged in and operating perfectly fine - then suddenly disconnect from all devices.

Matt, Customer Support
We always try to ensure our customers have exceptional experiences with our products and we apologize for the connectivity problems you're seeing with our ST4300MINU3B. If you've got all of the ports on this hub full and there are high-power devices such as a portable external hard drive connected, you may see some issues due to power constraints as this hub does not have a separate power adapter and draws power directly from the USB port on your computer. However, if you're not using any high-power USB devices or do not have all of the USB ports in use, then there may be an issue with the USB cable. We'd be happy to speak with you to find out what's causing this issue and help fix it for you. You can contact us at where our Technical Advisors are available 24 hours a day, 5 days a week to provide support.

(5 stars) Great Hub

By: kenlanier
The Startech Hub has worked solid for me. I have been using for several months using multiple devices ie: sdr radio, ham radio stuff and I have been very impressed with its performance and ease of use. Highly recommend Startechs products, ROCK Solid!! -Ken
