Review on 10 Packs of Adhesive Hooks: Heavy Duty Sticky Wall Hangers - No Nails - 15 lbs (Max) - 180° Rotating - Seamless Stick-on Hooks for Bathroom, Kitchen, Office & Outdoors by Kholar Irvine

I actually bought these to hang curtains in my solarium. I rent and was not allowed to put curtain rods and the windows were too wide to use tie rods. Against this background, my porch bakes in the midday sun and FROST in winter. The hooks are still stuck! Removal isn't too bad either. They are STICKY but the residue rubs off with very little effort and no stickiness is required. I glued them in and put them back in and tried to get the curtains right. If I hadn't pressed them down before taking them off, they could be reused. The ones I put pressure on ("live and learn”) before the removal were no longer good afterwards.
