I tried the Topsy-Turvy but found I liked the DELUXE Topsy Turvy Tomato Tree even better. Instead of the water dripping out of the bottom onto the plant hanging down, the Deluxe version has 3 ports in the side in which to plant the tomatoes. So they grow OUT and down... and the water draining from the bottom of the bag doesn't drip onto the plants.
I have a Flavor Wave and have never used it, but I PLAN on using it.
The Green bags that help keep fruit and veggies fresh WORK.
Haven't used the Magic Bullet, either.
Bought one of those major, huge, power wisk things... Thunder something.... worked great but really too powerful for me and kinda heavy, plus it's a pain to clean. Stores nicely in its stand, though.
