The best thing about cryptEXT is that it works great with Google Apps! There isn't anything I dislike so far except perhaps some of its more recent updates have been buggy (but this can be said across most software). As long as you are using google apps then there's no reason not too use CryptExt - It encrypts all your data in transit between sender/receiver email addresses making sure they're safe from prying eyes if someone gets hold off their phone or computer etc.. If i had any complaints atm; would probably involve when sending attachments over 10MB which has recently increased by 1GB due possibly to bandwidth issues but other than those minor niggles everything seems fine now though.
