I have been using the Dental Pod and Retainer Brite tabs for a little bit now. It’s more expensive than some of the ones I looked at, but it has been working great so far and I like the smaller footrprint / look of it. It definitely cleans better (and is much easier) than just using a soapy toothbrush on my Invisalign retainer. That being said, I have not owned it long enough to say if it’s truly BIFL or not.
