Item arrived in good time but it is not the equivalent to a Bestway III cartridge as the hole at each end is slightly too small for our filter. However, if you just slit the hole to make it larger then you can adjust it to fit and it does the job well. I just feel this should be mentioned in the detail section on the Castle Hot Tubs website.
