Only real criticism of the andy stand is that it holds the bike where some of the work you’d put a bike for takes place, so it either obstructs or prevents you working on the crank or bb. Its not that clear to me whether you can turn the cranks while its in the stand so gear adjustment would be a query too.
The main thing for me though is that the bike is standing on the floor, so for any of the bits of the bike you most commonly work on you are working on your knees.
The seem like a neat way to display a bike but it doesn’t really solve many problems for working on one
