I didn't have enough arm strength (arthritis) to use our old metal caulking gun, but the Dripless ETS 2000 is so easy to use. If you have weak or arthritic hands, you'll know that this caulking gun requires so little pressure to squeeze that it even seemed like I wasn't pulling the trigger when I squeezed it. An added bonus is a built in cutter to cut off the tip of the sealant. I don't know how long it will stay sharp as I only used two tubes, but the caulking gun is worth it even without.
