OP, it's a big story with very small detail.
What's the brand of the stands? Can you post any pictures of them - teeth ?
If a stand should give up even to the pressure of your hand there must be some visible defect.
If they failed on you and you can reproduce the failure and still keeping them ?
You're out of your mind. I would not even keep them around - destroy and throw them, otherwise someone will find them go "Yippee. scored me free stands" - and you know what follows next.
