I have a crib tent, but never needed to use it (thankfully). But I did let a friend borrow it b/c her kid would climb out of the crib at night and climb over his gate at the door. His parents did not sleep much due to this and neither did the kid. Anyway, if you feel she is not ready for the toddler bed, but she wants to climb out of the crib (and risk getting hurt) then I would say why not use a crib tent. I mean it won't hurt anything to use it. She will or can get hurt though if she falls on her head trying to escape the crib. My friend said it worked great for her and she loved it.

Personally I always put my babies in Sleep Sacks, and having their legs covered made them a bit less inclined to try to climb. My first one was not a climber by nature and my little one is probably still too young to be seriously trying, so I have yet to see. I kept my big one in her crib until 3, and she wore a Sleep Sack until probably around 2.5. Never tried a crib tent.
