I use it.
Watch out for the following problems:
1) When printing, you will have a very hard time setting up to print duplex, and it will not line up no matter how hard you try. I spent 5+ hours trying to get it lined up properly and it still is not perfect. The paper that MGO ENt sells is very expensive so test out your printer with cheap paper first.
2) remember the code that you recieve after you buy the software. If you loose your code you will have to buy a whole new copy of logbook pro. NO MATTER WHAT.
3) There is no 1-800 number for "help" with the program. If you have any problems, you have to get help online. There is no body to talk too.
4) The logbooks for MGO Ent are very expensive, as is the paper. The logbook binders will only take 100 or so pages. They say that the binders are 3/4 inch. in reality the rings are only 1/2 inch.
Other than that, the program works pretty good although I think it could be improved, and the product support could be improved as well. If you are the type that needs to talk to a human when you are having problems, I do not recommend this program. If online support is o.k. for you - go ahead. The extras are also very expensive.
Cheers.
