I find the device but still great, as an old "floss muffle" I use the device 7 days a week and on Sunday also normal flossing. This is certainly better than a week to use only once flossing.
This can be seen simply from the fact that the device is still on "stuff" from the interdental spaces "shoots" after having dutifully cleaned for 2 minutes with a good (Oral-B Triumph) electric toothbrush.
I myself have quite tight interdental spaces, and yes, it worked for me in some teeth even to run at all. When I found the right angle for each tooth but it has worked perfectly, and that's at some point all by itself (keyword: conditioning).
Criticisms:
- No charge indicator (the device is, after all, almost as expensive as an excellent electric toothbrush, as you can this really be expected).
- The device is balanced unhappy and has too small footprint, it is very easy to if you touch it.
- No travel cover or other is, you buy only the device with an attachment.
I think it is quite a good idea, currently pays to this idea and the research / development costs still noticeable with.
Nevertheless, a buy recommendation from me who can not wait should possibly wait for the next generation, I'm sure this system has a future.
