The filter worked great.
It's a filter, what do you want me to say about it. It filters. Filters are too expensive, even when this is one of the cheaper options. I would replace them every two months if they were more responsible.
As mentioned in a lot of reviews the hole size in the filter to fit snug on a Caldera tub should be 3.5"" these filters are stated to be 3.625"" and mine was closer to 3.56"". It was enough big to float off the mounting tube. I measured the distance from the bottom of the filter basket to the top of the filter and cut a piece of 2"" PVC to that length drilled two holes in it and zip tied it to the bottom of the basket as a spacer to hold the filter down. It is working out fine now. This filter was about 20 bucks cheaper so it was worth making the fix.
Great Spa Filter
