If they are offering a filter solution that allows a lens cap over the filter, I'd probably buy it. A variety of filter colors and a quick-change mounting scheme would be welcome too.
My current filter prevents me from using a lens cap, which leads to some scratching of the filter when it's out of the water. My filter is also hard to swap (requires tools) and so I only use one color (shallow/med). It does a really great job improving shots <40 feet, but deeper shots should ideally use a darker red filter.
My avatar photo is a video grab, shot at about 15 feet with the shallow/medium filter. Profile photo is a still shot around 30 feet. No color correction needed. It shoots very true to color at these depths.
