I have the the topsy turvy for strawberries, they were getting rid of the topsy turvy late in the year so got one it was like $2 or less
PRO it worked well for strawberries. I may replant some this year. having the plants in one place was a little easier but i still failed them (see below)
CON, after you add the dirt and the plants it weights a lot, make sure you have a god stud to hang it into. I never did hang it but it worked find
I also negleted it some in last years hot summer and it dried out some as I lost two plants, so watch how you water it.
