Balconi red tomatoes - trailers?

I was looking online for advice about Balconi Red tomatoes, and I came across a thread on this site where someone said they'd grown these and they didn't seem to be particularly small plants or fruit - I noticed that this thread was in 2021 - I just wanted to say that I grew these tomatoes from seed last year, although I'd bought the seed in late 2021 - I had the exact same experience - the plants were in pots slightly  bigger than 30cm, but not much - and they were very sturdy and didn't trail at all...I'm not really complaining, although with a small paved garden, all my tomato plants have to be in pots, so it's much better if the plants actually do what it says on the packet...
