They seem to be marketed for educational purposes. You could simulate them in software easily. They could be useful for research, but they're not directly useful for computing, except as a novelty.
"Gemini Mini is a conditionally portable, entry-level 2-cubit system... The device has built-in CASTOR software, allowing it to simulate the operation of 8 qubits."
Not sure what benefit you get from using real qubits vs just simulating them, even for educational purposes.
Real qubits have flaws, and you could experiment to see under what conditions they work better or worse, like by applying magnetic fields. Simulated qubits are presumably flawless, and so you can't experiment with them.
