Pretty nice! Flexible as heck
Comfortable and easy to insert, but the jewel pops out of the plastic easily. So easily that this is what happened to me twice. On the first time I found the jewel but had to fish the plastic out of my nostril, panicking that it would be inhaled deep into my sinuses. I reinserted the jewel and tried again. The second time I could not find the jewel, so the thing is useless. Good idea, but not secure.
