Haven't tried any of them yet but was surprised to see multiple units in package, my current piercing has been in for ages and has been difficult to remove, also all of the units supplied while looking normal all appear to be glow in the dark. Will test once I have another locally purchased tongue bar of high quality incase I damage my current one and the sellers supplied units are not of high enough quality to be used daily, will edit this review once I have tried and worn a unit for a couple of days to a week eith or without issue
beautiful!
