I thought I'd give this a try as I have several rental properties and other landlord/tenant programs didn't really appeal to me, mainly because they are so expensive (as this is!). I had no problem finding the screen shots on the developer's site. The links actually say “click here for....” so the developer may have added them since some of these reviews were posted, but when I looked at the screen shots I was sorry I had found them. Still, my curiosity got the best of me so I downloaded the trial.
First, the interface looks like OS 7 (OS 9 at best), but I really tried to reserve judgment pending the actual us of my free trial. It didn't hold my information (I had to enter everything twice-so maybe there's a steep learning curve or something :D), I didn't seem to be able to personalize it, and it kept crashing.
The price of $200 is astronomical for a program that looks like this and doesn't even work well. You're better off using FileMaker or Bento and making up your own rental database like I ended up doing. Then you'll at least have a program you can use for other things.
