recently i purchased an expensive 2.2m garden obelisk which was not 'fit for purpose'. the joints kept popping out after i had pushed them in and eventually i had to use black gaffa tape to secure them. after completion it was not stable so dispensed with the bottom 4 legs and secured the finished item to my trellis for the support of my passion flower. i could not be bothered with the hassle of returning the item. my previous cheaper metal obelisk from amazon was far better albeit this involved fixing screws which was time-consuming but made a great support for my clematis.
