Review: Worth it - This is the best cable mapper/tester I’ve used. It works reliably, is easy to use, and has been very accurate every time I’ve needed it. The battery life is also impressive — I only had to replace the battery after 4 years of use. A durable and dependable tool that’s definitely worth it.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Test the cables before running them
*by B***. on November 24, 2025*

Works great for testing connection. Simple to use

### ⭐⭐⭐⭐⭐ Worth it
*by C***S on May 16, 2026*

This is the best cable mapper/tester I’ve used. It works reliably, is easy to use, and has been very accurate every time I’ve needed it. The battery life is also impressive — I only had to replace the battery after 4 years of use. A durable and dependable tool that’s definitely worth it.

### ⭐⭐⭐⭐⭐ Testing simplicity, like a Mod-Tap tester, using 2 AAA batteries
*by C***R on August 28, 2020*

The Southwire M400TP has a simple design with one button press and removable remote that stores in the unit, similar to some toning wands. It identifies opens, shorts, splits, miswires (reversed and crossed), short to shield, properly wired cross-over cables, and a voltage warning...a nice add. There is also a toner feature that allows tone on individual conductors, individual pairs, and on all wires simultaniously. Note: a toning wand is NOT included. Excellent instructions are provided. Documents reflect a 2-yr warranty. The brown case has a slightly rubber-like feel and easily fits in the palm of the hand and a tool bag slot. The cable tester's top RJ-45 jack has a dust/rain cap to prevent unwanted objects from entering that area. No expensive button cell batteries needed like some other testers. It ships with two AAA batteries. The screen also has backlighting for those times when you're testing from dark closets or beneath desks. A recommendation for the Southwire team --on a future redesign, possibly recess the mode button so it cannot be accidentally pressed while in the bag, and maybe a small microfiber pouch to cover the plastic screen while in your job bag. Overall, a really nice compact continuity tester with slick features. Don't change other things with this design, its close to perfect.
