I love that these cables come with Lightning, USB Micro and USB-C connectors for each cable and come in a variety of lengths and colors. I have tips installed in almost all of my devices (phones, ipads, headphones, etc.) and since each device has the correct tip, the cables are interchangeable so I don't have to worry about choosing the right cable - I travel with a power adapter that has five USB-A ports, I connect five of these cables and I can charge any device I connect the tip to, regardless of the type of cable it requires. It also reduces wear and tear on the devices since I don't plug and unplug the tips often (therefore the device power connectors are less likely to fail). It helps that the cables are protected from the magnetic field (reduces the chances of me accidentally pulling something off the table and breaking it). Because each cable has a small LED at the end, it's easy to find them in the dark, even at night.
