Review: Todo perfecto - Todo Ok
Review: Moving from a 12 year old Tripp Lite tool to this was a shock - If you are not familiar with desertcart Vine, it is basically desertcart trading free* products for honest reviews. You see a lot of Vine reviews that are cookie cutter and based on templates. I aim to make my reviews honest and non-cookie cutter (other than this intro and disclaimer). * These items are not actually free as Vine members pay income tax on the items they receive. Therefore, I will never order something from Vine unless I actually intend to use it. I think this is important for readers to understand because it means I will never order an item just to provide a fake five star review to a company. If I review something as good, it means I actually enjoyed using it or it fills its intended purpose correctly. Items that don't meet my expectations will be reviewed accordingly. Why I ordered this item: I do cable installs frequently for work, and the old Tripp-Lite tool I have is getting pretty rickety. That tool was over $600 when I bought it. I wanted to see if a cheaper model could hang. Likes: * Wowsers, this is the biggest upgrade I can imagine. * The old unit generated reports and this one does not, but other than that this new one is superior in every way. * It has new features that I have wanted (PoE testing) and the visual output is almost infinitely better than the basic display on my old unit. * I mostly use cat6 tests and toning, and this device does those very well. I toned three cables in our walls out and they worked like a champ. I also tested a cat5e cable that was working but only at 100Mbps and found out that it had a short. * I will definitely use the PoE testing component as we hit PoE cameras all the time that have power issues, but I didn't have any PoE devices at home for me to test. * USB-C charging on both parts! The old one used 9v batteries. No likes: * The reports would be nice I guess, but I feel that the visual output on this more than makes up for a lack of exportable reports. I did not deduct a star for this because other than the first time job I used my old tester on, no client has ever wanted reports. Would I pay full price for this product: Yes, 100%. Final thoughts: If I had known I could get one of these for $130 I would have ditched my old unit years ago. This thing is crazy and will be an extremely valuable addition to my toolkit.

### ⭐⭐⭐ Ehh, it's okay but broke in 3 months with light use.
*by B***D on July 7, 2026*

So, it wasn't a bad tool. One thing I found very annoying is that if you have auto DHCP IP obtained, it would pull, say, 192.168.20.15 with a gateway of 192.168.1.1. However, if you manually try to set up the same configuration, it won't let you. It will make you use 192.168.1.15, and you can't do a network search this way. If you ping it, it will let you change the IP address in the ping screen, lmfao. So yeah, that was a waste for most of the time. When I was testing a network, it wouldn't work with DHCP because it couldn't reach the domain controller or something similar, so I NEED manual input without workarounds. Yeah, I use ping for things like this, and luckily I can do that with the workaround, but it would be nice to scan a network, lol. Anyway, now to the big thing: the wand side of the unit has stopped working. If I plug it in and turn it on, it makes odd sounds, beeps, and flashes the light, lol. But if I play with the buttons, it will go to its normal use modes. However, it will NOT charge, so now I don't have the second part of this combo, which has most of the cable testing functions, and it doesn't work without it, from what I could tell. Lol, so beware. It's okay, but it's not reliable, or something I would buy again. I'm going to donate the main part that works. Move On Buy a better unit. This was a pretty mid-priced unit; it kind of sucks that it broke.
