Plus and minus
The magnets are powerful and do work however, I have had some spools not work with them no matter how close together the magnets are to each other. Also had two of them break to pieces in storage. Make sure there is a barrier between them when storing. I also have one where the hole in the center is too small and will not fit over the bolt.

Fits the CRB Pro carriage perfectly and the tension is absolutely consistent once set to your needs. Springs work but this is a great upgrade!
