I really really like horsefields and thats where all my research has been. I have a friend whos just got two hermanns and they are saying hermanns all the way. Im saying horsefields
I don't own hermann torts, but my russian is AMAZING! However, they require a lot more room than hermanns because they like to wander. So it would not be ideal if you live i an apartment, or have a small space for your future tort.
I do live in an apartment however, he will have an outdoor enclosure at my parents house not far away. Also, i have a juliet balcony so he will get sun. I will just have to make sure i closely monitor temps and move him/give him lots of shade if need be.
