I was looking at it compared to the Red Sea Prism when I was buying. The disadvantages that I read about online was that the Red Sea didn't compare in build quality /longevity. Apparently, they can crack pretty easily. I'm not sure if this is so, it's just what I inferred from various reviews.
I went with the aqua C Remora with Mag 3, and it works really well. It seems very sturdy and I think it looks good as a HOB (it is square and black, kinda less noticeable sticking up than the round clear ones I think). It is also very quite with a paper towel mod, IMO. The downside is that they are really expensive, but a used one might just be the ticket...
