Known incompatible

Any mat with a single solid foam layer (no rubber underneath) does not work. The foam is too soft to grip the spikes. This applies to some entry-level mats (typically labeled "EVA foam practice mats"). For these, surface-sit tees like BirTee are a better fit.

What we mean by "compatible"

(1) Spikes seat fully without forcing. (2) The tee stands upright with a ball on it. (3) The spikes pull out cleanly when removed at end of session. (4) Visible mat damage after 100+ insertions is none-to-minimal.
