I've always wanted one of these cactus and now I have one. It's very healthy and quite large.
I ordered and paid for the larger Agave plans. I paid 600 USD for the 5 gallon size agave only to get the smaller size. I am not even sure it was 1 gallon. The Agave's were of good quality and the Cactus outlet provided good communication throughout the process, but beware of what you get vs what you order.
For several years I been wanting cacti and from month to month prayed and finally got it, never disappointment.
They look great in our front yard as do the firesticks in our backyard.
