I agree with those that say somewhat brandable. It is short and pronounceable, although possible confusion between ofrax, ovrex and ovrax. I tried to find sales that are of same length, and one letter possibly unclear from pronunciation, and the best I could find is oknan(.)com that sold for $788.
As well as short, pronounceable, memorable, radio test, the other aspect of brandable names is whether part of them associate with a business who will seek a domain name. I am not sure with respect to this. Let us know if Brandbucket approve it please.
