### ⭐⭐⭐⭐⭐ 







  
  
    Excellent tool!
  

*by M***Y on Reviewed in the United States on January 16, 2012*

I've had my share of hard-wired cat 5e network issues and always had to resort to the old "swap the cable" tactic to find out if a cable is bad.  Recently I had another issue and my current network is on a 8-port router with a 5 port switch.  The internet was slowing terribly and swapping out 50 foot long cables was not practical.  I bought this tool and will never go backwards again!  All my cables tested fine.  My router had taken a dump...Our local Lowe's had a tester that looks exactly like this Extech and they had it priced at $59.  Needless to say this Extech was a lot cheaper and even had free shipping!This is not my first Extech purchase so my previous experience definitley help me make the choice of what label to buy.  I was not wrong.  You can't go wrong with the price and features of this tester!  Buy one, you'll be glad you did.

    Never quess again
  

*by C***L on Reviewed in the United States on February 15, 2013*

I'm pretty experienced at making cables, but some times, when you look at the colors, they look good, but they aren't correct. For years I just relied on my abilities, but now I rely on a network cable tester. It works as advertized, and I would recommend it for anyone that makes their share of cables.

### ⭐⭐ 







  
  
    There's better out there
  

*by P***P on Reviewed in the United States on December 8, 2013*

I don't care for the slow pace of the test, it routes through each pair one by one as you wait for it. The switch is a hinderance as well, especially for those with failed memories.
