Wondering if anyone has tried the new(ish) Teething Egg, and if your LO likes it?

DD is 6 months and seems to be working on some teeth. Her current preferred teether is her own hand (which is generally unsatisfactory after a few nibbles) or my knuckle (which is gross from a germs perspective, and kind of hurts!) we do have a Sophie teether (with the loops) which she plays with, and one of Sophie's friends (which is too thick in most parts to fit in DD's mouth). The makers of the Egg claim the shape makes it chew-able in even small mouths, and I'm wondering if it might provide more resistance to her bite (similar to, um, finger bones)....yet I'm reluctant to shell out $20 plus shipping on a whim sight unseen. 😊

Thanks in advance for any reviews!
