Bag Stands?

Has anyone tried those heavy bag stands? Are they any good or do they move around. Doesn't seem like the bag has much room to swing. Any thoughts or recommendations? I can't hang the bag where I live so I was thinking about getting a heavy bag stand. Title? Century? Anybody that can offer advice? thx

I got an Everlast stand a few years ago.The bag didn't swing much but the stand rocked back and forth when i laid into the bag
