I have been doing a little research on them as they are based on the TM21
from what I can gather so far, there is no reverse function, the scales are separate from the bowl (ie you have to weigh into something first on the side).
Everything on the videos seems to be cut a lot smaller than we would with the TM to start with (more time consuming)
I haven't been able to work out if you are able to use the rice basket with the varoma as yet ...
Some would like the stainless steamer - but they do get very very hot.
I did like the idea of the steamer locking into the bowl like it did. Not sure if I could cope with that being permanent though as my steamer is often on and off the bowl as I cook. Would be a nice option if you could get it.
anyway that is my observations from watching the videos the last couple of weeks
