Bean Tower

[Adenn1]

Has anyone used the bean towers sold by places like Gurneys or Henry Fields:

Sturdy 6-foot, galvanized tower assembles in minutes, supports at least 12 plants. Keep your beans up off the ground, so they stay clean through the hardest rains. Makes harvesting easy, too. Tower folds for storage. Economical--can be used year after year.

I know that I could make my own...but with $25 coupon from either company...the cost of two of these towers with shipping and handling and tax would be $22 each.
