Opera browsers are returning as chrome (tested in OSX, multiple opera versions, windows tested with latest opera), it looks like you are parsing the UA to find the word 'opera', which is not in the opera UA, however the word 'chrome' actually is in the user agent so it returns chrome. As far as I can tell the only unique identifier to opera is the string 'opr/26.0.1656.60' (replace the numbers with the version) and really old versions contain the string 'Presto/'
The regex that works for me is /OPR/\d{2}.\d{1}.\d{4}.\d{2}|Presto// however it would be nice if we didn't have to have a separate rule from the Detectizr stuff.
