Hanging Tomato Planter Do The Upside Down TopsyTurvy Tomato Planers Really Work Well?

Do the upside down TopsyTurvy Tomato planers really work well? - hanging tomato planter

Has anyone tried to hang the Topsy Turvy tomato planter? Are they working well? I live in an area where there is plenty of sunshine throughout the year, but I would spend most of my garden space for other vegetables. I hear about all the good or bad experiences you've had, so that all the wise advice. Thank you!
