I do soil blocks as well but if you place them too close and on a solid sheet the air pruning doesn't work
It took awhile to get the hang of making them but I really like them. I have the mini, the 4 and this year I got a 5 block maker. My son got the super big one for things like cukes, etc but they're so dang heavy! I just prefer to direct sow cukes and melons.
