Buying advice
Magnets work only on magnetic steel pots. For non-magnetic containers, use glass or stainless food-safe weights placed on the bag, or clip the bag to the tub edge. A rack solves the same problem with less fiddling.
FAQ
Do I really need weights?
Only if bags float in your setup — fattier foods and trapped air float more. It's a small fix for a real problem.
Are magnet weights safe?
Yes — they're designed for sous vide, coated to avoid scratching, and hold firm through the cook.
What about glass weights?
Glass and stainless food-safe weights work in any container — just make sure they're food-safe and rated for heat.
