Customers have negative things to say about the ease of cleaning the silicone sealant. They mention that it starts oozing out the bottom, the plastic pillars break off, and the silicone leaked on their hands. The silicone does tend to get a bit messy, and it's difficult to clean out.

"...One difficulty I had was the sealant was more inclined to come out in the back of the tube then at the tip as designed...." Read more

I used this to repair a leak in my Ox Horn Mug. Non-toxic and sealed the leaks that existed between wood base and horn, as well a small crack within the mug itself. Yeah, worth the money.
