Does basic checking for breaks in cable and connection of RJ45
There seem to be a few very similar testers on the market for roughly the same price. I was able to prove to the electrician that put in my network cable that they had wired the connectors wrongly. Cheap and simple to use.

Simple but it works
Have used for about a dozen patch leads now, and has already helped spot a couple of bad crimps. Very simple to use, and has held up well. Don’t think it’s the most durable item ever made - switch a little flimsy, and I feel the way the two halves slide/snap together won’t last the test of time, but to be honest it’s been perfect for my use

LAN tester
Read a few of the reviews, decided to go with this one, cheap and does the job, ok for occasional DIY use.

Cheap and cheerful
Simple electrical CATx cable tester. 8 cores plus ground.Plastic, cheap, just like any other until you spend big bucks on a tester that runs protocols.

Useful and cheap
I bought this when I received a faulty, long Ethernet lead and decided to quickly repair it. It was easy to use and the results easy to understand. The lead was repaired and retested very quickly. Having received a free replacement lead, I now have backup
