Hunanbang Bathroom Drilling Adhesive Toothpaste Bath Review

I bought two of these kits and the adhesive is terrible. 3 out of 4 have already fallen. I LOVE the design and how it looked once installed so I'll try to come up with my own glue but man I'm struggling to find bottle cages like this that come with glue that actually works. I don't even want to think about how much I've spent on previous purchases of such items, nor wasting material on useless products. :(
