These floaters continually break. The guard that stops the tabs from going into the top is very flimsy and the tub comes apart from the floater. I do not recommend this floater

used to replace similar one that seperated at the base

Perfect, as described !

we have had these before and they are durable and hold up very well.

Used in a spa. I like that it holds a good supply of tablets. Unfortunately, sometimes the tablets bind up within the tube limiting their exposure to the water. I do wish there were a way to ""quick release"" the concentric tubes over having to unscrew and then rescrew to the desired amount exposed. It's a bit tedious. Material of construction seems durable, thus far, but use has only been for a month or so thus far. We'll see how it holds up over a few years (unlike its predecessor!).
