## Why people recommend it

- Sorts loose cables, discards bad ones (4 comments): "This device let me categorize all my loose cables (and throw out the truly terrible ones). It was worth every penny."

([source](https://news.ycombinator.com/item?id=49658266)) "i've found a few bad cables that would intermittently fail." ([source](https://news.ycombinator.com/item?id=49301643))
- Shows what cables actually support (3 comments): "for my use case, i.e. verify what's actually in the cable (not blindly trusting the marker) the latter is sufficient and very ergonomic" ([source](https://news.ycombinator.com/item?id=49301385)) "I have enjoyed my Treedix - now almost every cable I have has coloured labels for what it supports and what ends it has" ([source](https://news.ycombinator.com/item?id=47994376)) "Gives you all sorts of information very quickly, including resistance levels and capabilities."

## What people warn about

- Only reads markers, limited checks (3 comments): "Your $40 toy won't help with that scenario and you will be back at square one." ([source](https://news.ycombinator.com/item?id=49310053)) "it's definitely better than having nothing, and tests resistance as well" ([source](https://news.ycombinator.com/item?id=49205199)) "All those cheap $40 boxes are doing IS reading the marker."
