first class holder takes 8 tablets so last a long time in my hot tub .

Great price great value. It works in my hot tub. I replace it about every three years. They last a long time if you take care of them.

Picked this up because I needed a floater that could actually hold up in a hot tub without tipping over or dumping way too much bromine at once. This one’s been solid. The adjustable vents make it really easy to dial in the right amount, and it stays closed even when the pump kicks on. I use 1" bromine tablets, and it holds plenty without needing constant refills. The build feels a lot sturdier than the cheap ones that crack after a couple of months. It just floats, does its job, and I don’t have to mess with it every day. Exactly what I wanted — drop it in and forget about it.

The product took a while to arrive. Seems reasonable quality compared to other similar types. I bought this because it says it is much more adjustable and can be used in pools and spas. I installed it on the minimum opening of 0.5 (info says 1 for spa of the size quoted) one evening and the sanitiser levels went crazy to over 20 PPM. This product is just not suiatble for spa use. i contacted two leading spa companies who both said these should not be used in any spas.

In the past I made a plastic bottle with holes in it, added a few rocks for bottom weight and this seemed to work OK but not like this gadget that I thought I would try. This dispenser is perfect for my small 120 gallon hot tub.
