We currently use an Arizer Solo with a showerhead water tool (and the power adapter). We love how efficient it is and how easy it is to use, and it follows us from the computer area to the living room to the bedroom every day. Unfortunately, we can't always be in the same room together when both of us want the Solo at the same time. At first, I thought we'd just buy another Solo and water tool. But then I started to wonder, is there something out there that could work better for us? Here's what we're looking for: - simple to use - I don't want something I have to be constantly fiddling with. - I have no preference re: desktop vs portable. if it's a desktop unit, it should be something that can be put on the table we have against the back of our couch and be used with minimal interaction, aside from something like occasional temperature adjustment (we don't have room for a coffee table to set it on in front of the couch). - whip vs bag? I have no experience with either, however I imagine a whip would be more appropriate/easy for us to use with the above requirements. I am open to corrections on this, however! - water. I don't have a huge problem with coughing, but my husband does - so we'd like something that supports using a water tool somehow. - cost - this isn't really an issue, for the right unit. However if I'm going to be paying more than the cost of a new Solo setup, it really has to be worth it, and incredibly reliable. - edit to add: currently we're only using dry product. If something you want to recommend does concentrates and whatnot as well, great - if not, no big deal. Currently the Solo does fit all our needs, and I'm happy to buy another one if that really is what's best for us. However if there's something out there now (or coming soon) that does the job better, I'd really like to hear about it!
