It's conincidental you asked this today. I was going to do so yesterday, but after visiting the website, I decided it was just too pricey for me.
While I could afford it, the scents were odd...focusing on specific "hotels" or something. Maybe I didn't get it, but, I decided it was too sophisticated for my taste.
I just want to find a decent scent that doesn't cost a fortune and works without having to think too much about it. 
Right now, I use reed diffusers and I'm sticking with them for now.
Pier 1 used to have wonderful diffuser scents that changed with the seasons. I had a store nearby and would always have a good supply on hand.
Sadly, Pier 1 stores are no more and the online store has a somewhat limited selection. It's best to get them on sale if you can.
While they used to carry the larger bottles as refills, I see they now only carry smaller sizes. I'm thinking of trying some of the pumpkin spice scent which is now on sale. Not sure what their shipping is, but that will be a consideration.
I've tried numerous brands of diffuser oil and....most were a miss for me. At best, most are subtle and have limited throw. At worst, they are undetectable unless you are standing a few inches from the reeds
I was a devoted candle burner and gave up because no matter the quality, they sooted the walls even if you didn't see soot coming out. I've tried plug ins, sprays, wax warmers just about any scent gizmo known to mankind.
All with the same, limited throw.
In the end, the diffusers were the most economical and least offensive.
Sorry to be so long winded, but I cannot seem to express my thoughts any other way.
I haven't tried the Aroma 360, it looks interesting but butting in to say like @Witchy Woman I like reed diffusers and my very favorite is
Frasier Fir Pine Needle Reed Diffuser by Thymes
It's a little pricey but after buying the set up you can buy the refill oil from Amazon....
I don't watch the candle shows, so not aware of the Slatkin diffuser products.
My experience with diffuser oil is that most of it has very little throw. Even the really expensive ones. If you have it in a small room, it has some impact.
My house has large rooms and 10 ft ceilings and I suspect that the scent drifts upwards and is lost.
Every now and then I catch a whiff and I think it does have a long term affect, but it does not hit you right away. Then again, I may be nose blind to the scents I'm using.
One container does little or nothing, so I do tend to put multiple containers around when I want more strength.
In all honesty, house scent can be tricky. You don't want it so strong you have a headache, but you do want to smell something.
I'm just not willing to invest a great deal anymore. I once spent a small fortune on multiple Lampe Bergers and...in the end, I hated them. Somehow, the scent never smelled clean to me. I gave them all away.
