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.

Cap fits over my engine heating core perfectly. It works just fine. The strap has a long slot that makes it easy to get over the three-prong plug.

This cap is not made of a synthetic rubber. If you need something that is the least bit durable, this isn't it.
