I have 6 canes in my back garden, planted about 4 years ago? They are quite prolific, the fruit is quite large, soft, but not outstanding flavour.
The only problem I have with them is in the pruning.......because they produce fruit summertime and into December sometimes, I never know whether to treat them as autumn fruiting or not. Consequently I end up pruning them very lightly (probably underprune them if there is such a word!) If you cut them right down in Feb you miss the early fruit, if you prune them late summer you miss the late fruit, so... :-\
