Pretty good!

Meanwhile this is one of my two favorite ePub readers on iPhone. Almost all features to adjust design and readability are available.

I use it also for tests with own texts as ePubs written in Calibre (Windows). Here I find totalreader "over-sensible" - even slightest flaws in the code lead to problems like vanishing of content table, even if other readers on my PC show the ePub without problems.
