I worked with many installer, and was an installer once.
Carpet tiles are rarely used in flooring business. Mostly in commercial applications.
Easy to install, that`s why installers love them since its the same money, less effort.
You have to make sure the installer uses quality glue and apply it to the whole tile on a smooth, even surface.
Otherwise it will pop-up.
Disadvantage:
Later on, when you need to remove a damaged tile, it is not easy to remove it without damaging neighbour edges.
So seam will show. In addition, since it`s a new piece it will show color differences anyways.
There are really nice, thick, quality ones that they use in Hotels. But they are quite expensive.
