This stuff is pretty amazing. I've not used it before, but now that I see how it works and can see all its uses, I'll be keeping it around for a multitude of other things.
Step 1: Tape, scissors, and Band. Check.
Getting ready to cut a swath of tape.
Step 2: Cut the tape.
Cut a length of tape about 4 inches long.
Step 3: Split the width.
Next, cut the tape lengthwise (in half). You can use one piece for one side of the Band, the other piece for the other side of the Band - for double protection.
Step 4: Wrap it up.
Take one length of tape and wrap it onto itself around the width of the Band strap. Make the wrap pretty tight. The tapes bonds with itself instantly.
Not bad.
Not bad. Not great. But, protective. If you wanted a fashion device you'd have bought an Apple Watch.
No voiding of warranty.
All you need to do to remove the tape is snip it at the bottom where it sits against the Band's strap material. Remember, it only bonds with itself.
