Product review (4 stars): Saying on well without glue!
These don't come with glue and it doesn't seem necessary. Have had these installed for a couple of weeks WITHOUT glue and they're staying on great! They're just a bit difficult to push onto the tines (or I'd have made sure to use glue). You have to align them just so to get them on and then push down quite firmly. All the air seems to be pushed out this way leaving 'almost' a vacuum keeping them on. I'm pleased!
