I love LOVE my little iCare starter kit and now have 3 of them. I use one every day, all day long (trading off daily) so I need a new coil at least every 2 weeks per unit. I ordered seven 5-packs of coils. Shipping was in a padded envelope with no protection for the coils other than the manufacturers packaging box (light weight, simple cardboard NOT meant for shipping). Of the 7 boxes, none were totally smashed, but all were damaged and 3 of the boxes had opened up and the 3 packets of coils were loose in the bag. Hopefully, they all work.
