I like that it's free for personal use only! It does what all spell checkers should do.It can be user friendly but not by much. Sometimes sentences are checked before you hit submit which isn't ideal if something more technical is needed for your project.If using web tools then having multiple dictionaries available will provide greater coverage than what free apps come with.For non text editor projects this application works very well as long as we don't need the other features they offer such as copyedit etc. I like how easy it is to use! It's fast and accurate with no lag time at all. Sometimes when you have more than one word that has been spelled wrong (or even if only 1) there will be multiple options for what was intended by your writer or editor which can lead to confusion. The spell check function works great but sometimes its not as thorough as i would prefer so keep this in mind before purchasing. We are solving our issues regarding misspelled words within documents/emails etc.
