junk the nozzle has a spray tip that can come loose and end up lodged in your nose [SEP] i tolerated these poor performing devices because of the good price but when i had part of the nozzle come loose and lodge in my nose that was enough it took a lot to blow it back out was almost stuck in my nasal cavity no nasal mister is worth that riskon top of that these leak if they are not upright carry them in a bag or a pocket they leak they also do not last long enough to dispense the fluid in them the nozzle literally wears out and becomes non misting pump that barely works spend the extra cents and get something that works
