The company, after two emails, and a phone call,,, refunded the product cost PLUS the labor to replace the silicone.

I will test before use,,, now.

Agreed! This happened to me a few times, using silicone caulking for windows and/or tile and bath. Sometimes I've had tubes where the caulking where so watery(thin viscosity) that the bead of silicone would drip/run off.
