No. We aim to be produce the best sink caddy so we tested this thousands of times.
Some people migth've been too enthusiastic to use the sponge holder they sometimes forget to follow instructions properly.
That's why we ask them the following questions.
1. Did you attach the clear adhesive on a fully clean and dry surface?
2. Pushed out all the air by rubbing the surface completely?
3. Waited 30min before clipping the sponge holder?
If they did all this and they're within the 30-day refund/return window, we'll ask them to send a photo of the adhesive, we'll check it out to see what went wrong and send a replacement if needed.
