Customer feedback generally describes the foam as effective for filling holes, easy to use and quick to dry, with positive remarks about strength and perceived value. Adhesion is less consistent: some report a strong stick, while others say the foam falls out of holes. That matters for buyers relying on the claimed fast grab, since the listing does not establish results for every surface or gap. Feedback also mentions mixed foam spread, so application expectations may vary.
