I did, and I actually went ahead and purchased it after reading reviews on other sites. There is also an older post about it in this thread (I found it after posting this one). I haven't started clinicals yet, but I can already tell that it is going to be extremely useful. I know it's similar to Nursing Constellation, but it does come with Taber's med. dictionary. I feel like this will always be a good resource since it seems like you are always learning a new word or abbreviation

You also get access to the online database. I know the first year for Nursing Central online is free...I'm not sure what it is after that and I don't know if you have to pay for updates (especially for the drug guide), but I'm sure it's not much.
It's sounds like those that use it really like it. I didn't read anything negative about it.
