I own many hammocks and I purchased this one for my daughter. Largely due to claims of how overbuilt and safe it was.
If you own this hammock, replace the carabiners. They are not safe.
I test all my hangs and the last one failed. Nobody was seriously hurt. I can think of many situations where I have hung in this hammock where I deffinitely would have been, or my daughter would have been.
I weigh 175 and here is a picture of the failure. You can see the second one is also on its way to fail.
Edited title to more accurately reflect problem.
