Wilko Blox, any good?

[FissionChips]

Anyone have any idea if the wilko blox are any good? Do they fit well together etc?
I could buy a few blox sets for the price of one Lego set, don’t want it to be a waste though.

My DS (11) is a Lego addict expert.
He doesn’t like the Wilkinson’s ones as he says they don’t fit together as well and aren’t very good quality.

I bought a small set from a charity shop and vowed never again. I really struggled to get them to stick together.

Baseplates are fine, blocks are not..
