Basic continuity testing perfectly for £10 – ideal for home network cabling
Bought this while renovating the house. I’ve been installing cat7 network cabling to various rooms for TVs, wireless access points, and PoE CCTV cameras on the exterior. Previously I’d been borrowing a Fluke network tester from work whenever I needed to check cables, but figured it was time to get my own rather than keep lugging the work one back and forth.At £10 this is obviously a much more basic device than a Fluke, but for what I need it does the job perfectly. Came with the 2 x AAA batteries required which saved a trip to find some.Setup is dead simple – you’ve got a master unit and a remote unit that split apart. Plug one end of your cable into the master unit and the other end into the remote. Flick the switch and the LEDs light up to show you the pin-to-pin connections. If all the lights sequence properly 1-8 on both sides, your cable is wired correctly and has continuity.For my use case of doing basic checks on freshly terminated network cables to make sure the wiring is correct and there’s no breaks, this does exactly what I need. The slow and fast test modes are useful – slow mode lets you see each pin light up individually which is helpful when you’re checking the actual wiring order.The split design is handy when you’re testing longer cable runs or cables that are already installed in walls. One person can be at each end, or you can just leave the remote plugged in at one end and walk to the other end with the master unit.Build quality is basic plastic but feels sturdy enough for occasional home use. Wouldn’t want to drop it repeatedly but for the price it seems fine.Obviously this isn’t a replacement for professional network testing equipment if you need to check things like signal quality or PoE voltage, but for straightforward continuity and wiring checks it’s perfect. Saved me having to borrow the Fluke from work every time I terminate a cable.For £10 it’s great value if you’re doing any network cabling work at home.

Simple but good network cable tester
I picked up the HT812A cable tester to check some Ethernet runs around the house, and it’s proven to be a practical little tool. It feels compact and lightweight, yet the ABS casing gives it enough sturdiness to handle being carried around in a toolbox.It supports RJ45 cables (CAT5, 5e, 6, 6A, 7) as well as RJ11 telephone lines, which makes it versatile for both network and phone wiring. The tester quickly detects common issues like open lines, short circuits, and miswiring. I found the LED indicators clear and easy to read, showing pin-to-pin mapping on both the main and remote unit. The option to switch between fast and slow scan modes is helpful—fast for quick checks, slow when I wanted to observe each connection more carefully.The split master and remote design is especially useful for longer cable runs or in-wall installations. It allowed me to test cables between rooms without difficulty. Operation is simple with a single switch, and the shield indicator is a handy touch when checking different cable types.If I had to note one thing, it’s that it’s a basic tester—great for continuity and wiring faults, but not designed for advanced network diagnostics.Overall, it’s a reliable, easy-to-use cable tester suited for DIY users and technicians who need quick, straightforward cable checks.
