It

The menu bar icon is very large, this is inconvenient for someone with a laptop who uses complex apps with lots of menus. Whenever the app is running there is an invisible window open called BackDropApp which messes up Expose. The rain sound effect is the best one, but there is a very distracting pause every few seconds because it doesnt loop seamlessly. The developer has no real support page and no way to contact them, this doesnt make me very confident that they will ever fix these issues.
