Summit Ultramax a/s tires????

Hard times hit and I need tires. My Prius guy offered me Summit Ultramax a/s tires at a ridiculous price if included with some other work. He swears by them and installs them on all his Toro cars and his cars.
This costs less than half of what I was going to pay for Mich Defenders.
I would really like to know of anyone here has tried them and what they thought of the tire.
Thanks a billion.
No... I really do not trust reviews online.
