I think you need a third choice. Like, "I can take it or leave it".
I like mine. I got it in a group buy so didn't pay full price but I think I would buy one at full price anyway. I mainly use Dr Neau Tournament Manager on my laptop but it does lock up sometimes so I use the Genie as a back-up. I use it for additional games after my league game when I don't have time or want to set up TM again.
I use a set structure for nearly all my games so once I have it set up I'm good to go. But when I do want to use it for a different structure it is a bit of a hassle to set up quickly (I don't use the built in settings). I normally know when I need to do this ahead of time so it's not really a big issue but if I could pick one improvement it would be to be able to have more than one custom set-up stored in it and be easier to load it(I guess thats 2 things

)
As others have said, it is loud but I don't have a problem with that. My larger games have players in different rooms of the house so the volume means everyone can hear it. They can be modified if you are electronically inclined or a piece of tape helps tone it down.
