Wow! Perfect!
Fantastic product! I used with waterproof caulk the patch the seams in our concrete driveway. It saved my arms from having to use a manual caulking gun. Worked better than advertised. Very easy to load, use and handle. There was a comment from someone saying their gun jammed. The gun will automatically stop at the end of the tube. Love this feature! Don't try to squeeze the last drop from the tube and the gun won't jam. Again, awesome product! Very economical!

Great Little Gun -----But
I bought this for a problem I had, having to seal a window framing leak from the inside. Long story, However, what i needed was a long tip for caulking cartridge. I used a 1/4" plastic tube, about 7" long, sealing it to the end of the caulking tip. I originally had an admittedly cheap caulking gun, that actually bent as I was trying to extrude the caulk....plus, my hands hurt. I tried this, using the same type of tip (though new tip on new caulk cartridge). This worked GREAT, except, when i finished the tube of caulk (the gun travel was finished) what i found was that almost 1/3 of the caulk extruded around the rear plunger, so was essentially wasted. So more a caution about using a small diameter tube - which others said you could do. But mechanically I am happy with this gun, and it will be my go to caulking gun. Uses 4 AA batteries, which is nice, because i don't have to worry about another set of batteries to recharge.

Works great! Avoid wrist and hand pain of normal caulk guns
This thing has really come in handy! If you have wrist pain and need to do a lot of caulking this thing is so good. You have to get the hang of it and adjust the speed but once you do that you’re smooth sailing

Perfect if the manual trigger is difficult for you
I love this. I am 61 female and due to office work it is hard for me to grip a regular caulk gun and pump the trigger. I am always forgetting to push the trigger release when I set it down too. I just bought a house and I am renovating. Currently, I am caulking the gaps between the beams and bead board on the porch ceiling because they just left the gaps and caulking the gaps just looks so much nicer. With this gun I just pull the handle out, drop in the caulk cartridge, and push the handle in to load. Then I just hold the trigger and move it down the gaps. When you release the trigger it stops coming out. No more remembering to push the trigger release. One feature I didn’t think I would need is the led lights around the front. But it really does help when sometimes the caulk gun shadows the area you are in or it’s just a darker area. It takes four AA batteries so no finding compatible batteries like other tools where you have to have their batteries that cost a fortune and have to remember to recharge. I like that. I got this months ago and I haven’t had to change batteries yet. Overall I am very happy.

No speed control and comes out FAST
There’s only one setting, and it’s FAST! Be prepared to lay down caulk at a rate of about 8 inches per second. Works great if you’re doing an entire wall of baseboard and can hunch and walk quickly and smoothly. Otherwise, it just pushes out caulk way too fast for everything else, and there’s no way to control the speed setting. If only there was a slow/fast speed switch—then it would be amazing.

I see there are mixed review on this item , Took a gamble and I'm very happy with the results , I used plain clear silicone from what I call a normal tube from BnQ did the whole shower very easily. Would I buy it again if I had the choice Yes. Simple as that

Not good item too week to push calk out

This is an excellent chalking gun. Smooth and consistent delivery of chalk. It is great that it uses AA batteries which last a long time before needing to be swapped out. Use rechargeable AA batteries and have extra just in case. I recommend this and you’ll be pleased with the performance! Great price too.
