Floating Mini Spa Chemical Dispenser Chlorine Bromine Tablet Floater for 1 Inch Tablets, Spa, Hot Tub, Fountain, Inflatable - Perfect for Ground Pools

Works as expected

Works great! It’s pretty good quality for the price.

Super small but doesn’t need to be bigger for a hot tub. A bit difficult to open, takes some practice. Tips over a lot of it still works.

Works fine. Only issue was that it started collecting water inside and sinking. The key word here is 'reduced pressure difference' and that means if you drill a hole close to the top where you insert the chlorine tablets you will find that the floater doesn't fill with water anymore and won't sink. Maybe someone in the future will consider that and make them with a hole already in the top.

Got this for my hot tub works really well. It floats better than the other one. And I like the locking lid.
