Lip Balm Filling Trays

[riverbee]

has anyone used either of these trays to fill lip balm tubes? if so, do you like the tray or not?

Lip Balm Filling Tray Oval Lip Balm Tubes

Lip Balm Filling Tray Round Tubes

i switched to using oval lip balm tubes.  have someone redesigning my label, will post it when it's done......pretty cool!
for filling tubes i have used a pyrex, syringes from my vet, and a couple of small glass lab beakers (heat proof with handle) i was given from a friend of mine in medical research. slick! but filling a lot of tubes is time consuming.

i am thinking on trying this tray, but want to hear from others who may have used this gadget and your experience with it.

thanks in advance!
