Manual switches are often preferred by people who have tried them because there is no need to draw hard or for a certain length of time to make the atomiser work. You press the button as you raise the device to your face and the vapour is ready when you draw. I think it's a much better experience than having to activate an automatic switch by sucking.
Manual switch devices that I can remember are:
Janty Kissbox
Janty Dura C (when it arrives)
DSE801 manual
Screwdriver
Sedansa Omni
I can't think of any more at the moment.
See how you like the DSE901 though, that's a good device and you might find that it satisfies you enough to not need to look at other devices.
If you do look for others I suggest looking for a manual switch, efficient atomiser and USB cable options. Those things are all important for a good experience.
Hi Kate, What would be considered an efficient atomizer? How can you tell? Also would you please recommend some types/brands/ venders. Thanks
