Cateye Universal Wheel Magnet

I bought these to put on a second set of wheels so I didn't have to keep swapping over magnets. My Wahoo speed/cad sensor works well with this magnet and fitting it to the wheel is easier and more secure than the magnet that came with the Wahoo unit as this one does slip along the spoke. This magnet have two grooves so it with fit bladed or standard spokes.

It's a wheel magnet it works.

Good. Exactly as represented

As per usual super fast delivery and genuine parts

You'll need one of these if you have two sets of wheels and, like me, are a bit lazy about swapping the magnet for your Cateye computer from one wheel to another when you change wheels.
As it's a very powerful magnet, it's probably best not to store it in your wallet with your credit cards, Oyster Card, etc, as this will mess them up in a not-very-good way. Instead, you should attach it to one of the spokes of your bicycle wheel where it can do it's job properly.
