I have grown them but have never had one dripping with fruit as the pictures show but the yeild was good. Tumbler and Anmore Treasures will grow very wide and droopy so for me not a micro Tom even though the height is only a foot, I have had Tumbler cover a large area and yes they have been dripping with fruit.
I used to plant an early Tumbler to keep me going till the big plants came on, then a late Tumbler which I brought inside just before the frosts came, it went on a ceiling hook in front of the patio doors and lived there for a long time, eventually it would die off as do all determinate plants but it kept fresh and good well into the winter. It didn't work trying to keep the earlier one going though as it was well finished at frost time.
