Nice! My dad bought one of these back in 2009, we were going to install it in our old house in place of either our 2006 Toto Drake or our 2007 American Standard Champion 4, but we never installed it so we threw it away in 2010.
That has to be a Home Depot Value toilet, especially because of the factory water starvation. I also believe that the Lamosa Sahara evolved into the Vortens Vienna before 2007.
A front flusher with a short flush = not very good performance (as seen with the grocery bag - struggled to clear the end of the trapway like it was giving birth ironically!!! As well as the dishtowel not clearing). The bowl rinse is actually very good and the clearance would be the same if it had a longer flush. An 'Okay'ish' 5.5/10 as it is!
