When I bought this product I questioned spending $30.00 for a super glue kit.  But after having it for several months, I would not hesitate to buy another.  This kit shows that there are different qualities of super glue. And the various viscosities provide for a wide range of uses.  The thick gel version can be used as a filler for small spaces where mixing epoxy would just be too much trouble.  And with the included activator, the repair job is ready to use in a matter of minutes.
