Game changing tool. A relief to the hand
Game changing tool for caulking. This has replaced the manual caulking tool. I haven't had to recharge the battery for a whole house remodel. Used this to caulk baseboards, door frames, silicone tubs and sinks and windows. It is easy to use and the best part is that it stops when you want it to. No more cramps in the hand. The caulking gun although is heavier than a manual caulking tool but it's manageable and I would use this over a manual one at all time.

Great value
Worth the money to save time, used to seal the roof on my camper and it worked flawless.

Battery operated caulk gun
Much better than the manual caulk gun! Easy on the hands. It does what it's suppose to do.

Works great
Electric caulking gun? Didn’t know they made such a thing and I’m glad I found it. Got tired of buying cheaply made ones. This one is in a league of its own and I’ve been using it inside and outside. Well made, no mess and loads very easy. Happy with purchase. Thank you👍🇺🇸

it Makes the job a whole easier
I used the gun once so far and it worked great. I wish I had bought it sooner, it's very easy to use so I am looking forward to doing my tubs. The only issue I had was that the power cord I received with the product is for European socket so I has to buy an adapter from amazon. Other than that I recommend the gun but I will update if I experience any problems later.

No Regrets!
I’m using foam board to insulate my garage roof, which means every panel has to be sealed along the edges between each rafter bay. Each section takes roughly 25 linear feet of caulk. During the first round of installation, I went through five tubes of caulk, and when I finished, the battery indicator still showed full. Most of the time I was running the gun at its lowest speed, only increasing it when I needed to fill larger gaps. I even accidentally dropped it from the top of an 8-foot ladder, and it didn’t suffer any damage at all. So far, it has definitely been a “hand saver.” As for drawbacks, the only improvement I’d suggest is some kind of lanyard or hanging hook. When you’re working on a ladder and need both hands, it would be helpful to have a way to hang the gun safely. If it had that feature, I probably wouldn’t have dropped it in the first place. UPDATE: 32 tubes of caulk later, it still shows a full charge. Im not even sure if I will ever need the second battery. Also dropped two more times from 8 feet plus on concrete, no damage. If only everything was this good!! Changing to 5 stars and I dont ever do that.

A great tool to have if you're going to do a lot of windows, flooring, or a bathroom remodel.
Bought this tool for an upcoming bathroom remodel that will require lots of 10oz adhesive, silicon, and caulking. I knew I didn't want to be giving myself arthritis with the manual caulk gun, so we got this to make it easier. Pretty easy to get the hang of, you have to get use to how long it takes before product starts coming out of the tip. It backs off the pressure on it's own when you release the trigger, which helps to reduce extra caulk from dripping out of the tip, but you still have to be careful. I laid down an entire tube of black silicone for a rubber garage door thresh-hold, didn't have any problems with product coming out the back. One thing I would recommend: you never know when an older tube of product (or a new one with really thick consistency) might leak out the back side and you don't want to get it all over the gun and especially not in the geared plunger or it will get into the interior of the gun and gunk up the motor. So take a small piece of a plastic bag and place it around the head of the plunger. This way if any caulk comes out the back, it should only get on the plastic bag. I can't see any instances where it would get on the geared rod because the product will be on the walls of the tube. This just helps to protect the gun, and if it does leak, it's easy to toss that piece of plastic without getting product everywhere. When you puncture the seal inside the tip of a tube, rotate the rod/nail/whatever around a little ways to make sure you've created a large enough hole in the seal. It doesn't take but 20 seconds to check if the backside of a tube is leaking after you lay a little bit down. Just hold the release switch and manually pull the rod back just far enough where you can get the tube out of the holder and check it before you keep going. Also make sure you cut a large enough hole on the tip, if it's too small then the backside is likely to be an easier point of exit than the front side. The only time I did have that happen a little was when I was using an OLD tube of caulk on some basement windows and it had obviously dried out some. The new tube of caulk I used didn't have that problem at all. So just be careful, no one like's cleaning up product off the holder, the rod, or the gun. So use my plastic bag trick. If you need to lay a really small, controlled bead of product, then use a manual gun for that and also a caulk-shaping tool after you lay down the bead. If you need to lay a medium/large bead of product on a long run or a project where you're going to go through a lot of product, then this tool will be perfect for you. Use painters tape to mark off your walls/floors/ceilings/windows whatever if you really want a clean, professional edge to the product.

Not slow enough for thin lines
This gun would be fine for a thick adhesive or thick caulk jobs but absolutely worthless for thin caulk lines. The speed is too fast even on lowest setting to keep up with it. Soon, caulk is everywhere and it doesn't stop coming out for 30 seconds even with retract feature. Caulk everywhere. DO NOT purchase this gun if you are doing fine line caulking. Professionals with 1/4" spaces they want to hide, this is ideal.
