1 out of 5 eggsWon't test USB

Pros: Cheap -- as in 'inexpensive'.

Cons: Cheap -- as in 'poorly made'. NO USB capability.

Other Thoughts: Simply, this unit is not capable of doing what I bought it to do. I wanted to test some USB cables but there are no USB connectors on the device, only RJ11 and RJ45. The unit also appeared to have been previously used. There were dirty smudges on the front of the unit and the battery connector was bent. Finally, the tiny instruction sheet is in Chinese.

3 out of 5 eggsnot totally right

Pros: Simple to use.

Cons: The device came in defective, it would not turn off. I repaired it my self and now it works as it should. The device was missing 2 internal screws that held the switch. When the switch was secured the device turned on and off normally.

5 out of 5 eggsFor the price it's a winner!

Pros: Simple to use.

Cons: Manual is a joke.
[translated this manual like looks works. but, drift you get.] <- The expectation you should have of the manual.

Other Thoughts: Wow, this is a !great! tester for the price! The only complaints are that the power switch feels like your going break it when you "slide" it to the ON or "S" (slow) position.
You don't need the HORRIBLY translated manual to use it.
Worth the price, YOU BET!

3 out of 5 eggsIts ok

Pros: Does test network and phone cables. If you know the pin out for crossover network cables it even will test them.

Cons: It says in the title of this product that it tests usb. Good thing i didn't buy it for that because this does not at all test usb.

Other Thoughts: You need both the master and the remote to test. I tried using the remote end to test cables that are attached to my router. I didn't try the master this way because i did not want to short anything out

3 out of 5 eggsWorks

Pros: The units RJ45 connectors hold the cable well. Test all my cable quickly and effectively. Just plug main unit on one side of the cable. The easily detectable end on the other side of the cable.

Cons: The power switch is very stiff to move but for the price what can you expect. I received the product about a week after order it using their free shipping.

Other Thoughts: The tracking of this package was very difficult on NewEgg webpage. This product is not made for industrial usage. Power switch maybe their only weakness..
