Milwaukee 6560-21 12-Volt Caulk Gun with 10-Ounce Carriage Kit  Product Reviews

"It ain't cheap, but it sure is well built, and it sure lets me do caulking with my injured hand. I am a rightee, and I tore a ligament in my right wrist, which wiped out my grip strength. My left hand is ok, but it lacks the control of my right hand. With this battery powered caulk gun, I can once again caulk for hours. Its only drawback is that it is heavy, and is best controlled with two hands. If you have full strength, you do not need this powerhouse. But if you have lost strength, or need to use really viscous polyurethane caulks, then this baby is a godsend - if you can afford it. For me, it is a godsend, even at 200 bucks."

"The three stars is just a warning, not a critique of the tool itself. This might be the right tool if you use a caulk gun for a living, but it's inappropriate if you just want to caulk the trim in your house. I've used caulk guns for 35 years and now have elbow tendonitis that makes it painful for me to grip and squeeze. After installing about a mile of crown moulding in my old house (using a Paslode finish nailer, before the tendonitis - now THERE'S a useful tool!), I wanted to caulk the gaps at the ceiling. This tool is heavy and a bit fussy for detail work when you're up on a ladder. Much better to let the elbow heal, wrap your forearm with the proper bandage and use a manual caulk gun. Or if it's a big honeydo job that can't wait, pay someone else to do it."

"I have a boat restoration business and do alot of caulking with very thick materials. For years I have used an air driven gun but no more. This far exceeds my expectations. ONly down side is heavier than an air gun, but no hose to worry about dragging in wet caulk on teak decks, battery holds a good charge and comes with a universal (milwaukee) charger. You can also buy a 14 volt battery for a 2nd one at Home Depot, and works with gun and charger."

"You can not beat this new generation Milwaukee caulking gun for smoothness, power, long battery life, and designed -- it begs to be used ! I manage a Autoglass shop and my guys pump high viscosity urethane all day, any other gun would be punished to the max, not this one! I have used the older 2.4 volt Milwaukee guns for years and was happy, the 12 volt is 100 times better yet!"
