I have the Dreamstation Go travel CPAP with the humidfier. I also have the Dreamstation CPAP which was my regular CPAP until I went on a long weekend trip and used my Dreamstation Go for the first time and had really good AHI numbers. When I got home I decided to make the travel CPAP my everyday machine and found that I'm getting better numbers with it that the Dreamstation. I like that they both sync up with the MyDreammapper program on my phone and computer so it's easy to keep track of the data. I used the humidifier but took it off this week and haven't missed using it yet.

I bought the larger travel case which comes with a cloth bag for the mask, headgear, tubing and power cord. The larger travel case will hold the CPAP and humidifier or the CPAP and battery but not much else. The small case will hold the CPAP itself and nothing else. All of the other stuff goes in the travel bag that comes with it. It does make it easy for traveling.
