If you're learning bricklaying (properly) then forget any of these systems.  There are several variations on this theme, all aimed at the guy "who hasn't a clue".

Those pictures on their website show excellent brickwork, nicely jointed so NO WAY was any of that done as a first attempt at bricklaying.

I spent 3 years going to college (evenings) plus now over 30 years experience and there is a lot more to bricklaying than just bedding the bricks.

However, for a few quid you could get one of these gadgets and prove me wrong...........
