Basically, do the cable holder, BUT:
- They are not suitable for vertical installation. Then they do not keep extremely lightweight cable.
- With heavier or stiffer cables, such as normal Ethernet Cat5 cable, it sometimes happens that the cable holders are solved from the table
- More than a lightweight cables per cable clamp one should not attach too, because they can then solve also
In order for the cable holders are actually almost only used for light cable, such as micro-USB (the mobile phone charger), Apple Lightning cable, etc.
Since this type of cables work, there are still 2 stars. For all other purposes, I can not recommend the cable holder.
