What every best has:
Several local television news programs give Pro Caulk a hands-on test, including KFVS in Cape Girardeau, Mo., which finds that the tool works well on flat surfaces and gives it an A grade. WMBF in Myrtle Beach/Florence, S.C., says that Pro Caulk is no substitute for a caulk gun, but that it's a useful tool for those with little to no experience working with caulk. KLRT in Little Rock, Ark., has trouble getting a smooth finish and declares Pro Caulk to be a dud. A reporter for Popular Mechanics tests the tool and is impressed with how it smoothes both straight lines and corners. Reviewers on Amazon.com are mostly happy with Pro Caulk and how easy it is to use, though a small percentage didn't get the results they wanted and found the tool to be flimsy.
In the end, most seem to find Pro Caulk to be useful, particularly for those new to caulking projects.
