Very very useful in protecting frail cables. I even use it on my MagSafe chargers which are known to be extremely frail. No cables have frayed or broken since I added these little protectors. And they look good too!

Average protection for smaller diameter cables as it slips.
The price reflects its quality.

I use it on mobile and laptop cables. Sometimes it slips down, but the cables have a much longer lifespan.

Perfect application on cables, although it slips down occasionally. It is one of the most important investments if you are trying to give your cables a long lifespan

The cable holds very well, the plastic is moderately soft, I would prefer it to be harder so that the cable doesn't bend since I have the charger on a desk. It's worth it though to keep the cable stable for better durability over time.

Nice design but it should have been harder, in order to keep the cable straight, especially for Apple ones that get cut so easily..
