The clips/wraps themselves are okay, if you're trying to wrap thicker cords its not that great (like kitchenaid mixers) after wrapping the cord they come off. Some immediately, others a few hrs later.
Overall, disappointed and will try to return. They're a waste of money. Very, very disappointed. Do not recommend.
The adhesion is minimal.
These brackets should of been made with better material. They should have been made of better material, not worse. This is a bad example of a good bracket, not a bad.
