M12 12V Lithium-Ionen Akku-Klebe- und Dichtstoffpistole 283 g (nur Werkzeug)

The trigger on this thing is so smooth it makes every bead feel effortless, and the fact it's tool-only means I finally put my old batteries to good use. Was skeptical about a cordless caulk gun, but at this clearance price it's worth every penny just to skip the hand cramps.

My forearm finally gets a break—this thing pushes caulk out smooth and steady with just a squeeze of the trigger, no more wrestling with a manual gun. The 10 oz. tube size is perfect for bathroom and kitchen jobs, and the battery life has held up through multiple weekend projects.

Took my time laying tile in the bathroom and my hand never cramped once—the motor does all the pushing, so you just guide it. The 10 oz. size is perfect for a couple of tubes, and it's light enough to hold one-handed for a whole row.
