Outside. It's on entire bottom and about 2" up the sidesIs it on the inside or outside? I don't know the unit. Super glue should do the job if it's on the outside.
I used some Gorilla glue, very similar to E6000, that seems to be workingya I have 2 and although I haven't had them fall off it's just a matter of time. I was going to suggest a bead of silicon. Looks like they are glued on with a glue stick. Actually ...hot glue gun could work too.
