Helooo. Wow, I have not been on here in ages. Hope everyone is well.

I would like to get some information about FL-41 so that I have a better understanding about what it is for. Is there anyone out there that wants to education me or direct me to some awesome information about it?

Also, are there different frequencies that are recommended for certain things?

Are there different brands of FL-41 or is BPI the product to ask for when ordering?

Thank You,
Michelle
