Those are actually their newest model (stocked within the past month or so) cause I was looking at them when I was setting my tank up. I ended up going with a $8 checker from eBay that works like a charm. Made my own 4dkh solution per another members post here.
A $5 checker from eBay will work just as well but if you don't mind spending the extra cash, they are nice. I own (and have owned) a number of Cal Aqua glass items and will vouch for their quality. Just as nice as ADA glassware IMO.
I think it looks cool. I would only buy it for that reason. I bought the Oracle and have had it for 5+ years so they make good products. However, it's not like a drop checker needs something to compare to.
