Bought this to help rewire my house with ethernet cables, but I wish I had bought it sooner just to check patch cables. This product is extremely easy to use, but it is well worth the money for troubleshooting network connectivity problems or even piece of mind. Flip the switch and if all the lights show (in succession) then the cable is good to go. This product has saved me hours of troubleshooting. When my son's computer was experiencing intermittent connectivity I was able to rule out the cables in the wall and the patch cable as the root cause, and focus on the computer hardware and settings. Similarly, I was able to narrow down a different issue to a bad cable rather than replacing network hardware. Sure this device really does only one thing, but it does it extremely well and is the perfect tool to have ready for when you need it most. Note build quality is nothing spectacular, but for a plastic device it is solidly made. The included cables are very heavy duty and great quality. Overall a great purchase.
