I would prefer it a bit smaller, for the LAN cable I wanted it is large, it does its job perfectly but it is not that discreet.

It is large enough to pass USB cables from a gaming keyboard and mouse as well as a power external hard drive.

I have them behind the desk stuck to metal. They haven't yellowed, peeled off, or broken.

The -1 is because while everything is perfect on the desk, some that I placed on an interior wall, plastered with paint (it doesn't have the fine powder from the plastering) after about a year peeled off. It's not that they had weight, just 2 thin power cables from 2 drives, the modem, and the Philips Hue

I have used them to hold power and ethernet cables in the basement and they are great. I liked that they are transparent and I was able to replace the classic pins with the white plastic ones.

This range of 3M products with the "Command" adhesive strips are all really quite effective and strong. Allowing you to remove them when you need to (hence the "Command" in the name). They all seem to be good but they are all quite expensive for a few strips!

They were used to secure cables from lights with twine balls to a wooden surface, and they appear to have been securely fastened without any detachment in the 2 weeks they were installed.

I have placed them under my desk and so far they have not come off, they seem to have stuck well.

Update: 1 year later, none of them have come off!
