Works Great!
[This review was collected as part of a promotion.] This did not disappoint. The bond is incredibly strong once cured, and the black finish blends in really cleanly on metal and rubber. It’s super durable, weather resistant, and holds up well under pressure even in rain and heat.

Love that it’s black!!
[This review was collected as part of a promotion.] This is perfect for a leg that broke off on my Harmon speaker! I tried using hot glue and you can see how it didn’t stick! Not only will this be perfect, but it’s black to hide the epoxy of just make it blend in.
