These are small - and so aren't made to hold bridge cables. But for USB and phone cables they work fine. They have slots in each direction at a 90 degree orientation so you don't have to orient them when you stick them on. I found the adhesive hold very well.
very easy to use, but don't try to use one to bend and hold 3 very stiff and thick power cables, it simply won't hold for more than a day. Other than that, these are great. perfect for routing my cables to the underside of my desk.
PROS: rather easy to use, and you get a ton for the price
CONS: note the size, they are rather small. they can't hold a lot of weight for extended periods
Used these to wall mount 75' of CAT 5E. I think low volt staples / staple gun would have been a better choice. Staples would have been faster, deliver a tighter hold, and I have a feeling that when it comes time to remove the mounts, they'll strip off a significant amount of paint with them. I'm renting, so I was looking for a mounting solution that wouldn't cause any damage. Overall, the product does the job, though.
PROS: Easy to use, minimal equipment required (zip ties and scissors)
Plenty of extra mounts for future jobs
CONS: Time consuming
Mounts peel off somewhat easily (still mostly effective)
Before buying these, I used cable mounts that required nails and hammer which was a nightmare. Now I have these, things getting much more simple. All I have to do is stick these things on wall, and tie the cable with a wire or cable tie. Also, there are 100 of them in a box and they will last for long time.
