Query: I will never buy these again!

I was initially intrigued by these. I trim my cat's claws, but I forget sometimes, so I liked this idea. Also, it gives me a visual reminder when claws need attention, since they are colored. They are expensive, $15, but I splurged on them anyway. I'm not quite sure why other reviewers are complaining about them not sticking, the adhesive acts like superglue! I had a hard time getting the glue in the cap, but I did get it on my pants (my pants are ruined), hands (I had to unstick a couple fingers) and near (almost in) my eye. After that, they went in the trash. And, yes, as someone stated before this is a two person operation, but even then we had no luck. Best wishes to you, if you decide to try them anyway...
