This cordless 10 ounce caulking gun is best for high volume sealing and adhesive work, especially when pushing thick materials or clearing dried caulk from a nozzle. It makes jobs like brick expansion joints much easier than squeezing a manual gun, and the included two batteries add convenience for keeping it loaded and ready. The main drawback is control, since small detail beads on tile, countertops, and similar trim work can be harder to manage. Tube blowouts and dribbling can happen if the tip size and speed are mismatched.

I'm on my 2nd electric caulking gun (had a Ryobi, returned it), and I just don't think they're well suited for the most common use I have for caulking, which is caulking tile or a countertop. For doing large jobs, like using construction adhesive for big things, they're perfect, but for small beads, neither the Ryobi nor my current Milwaukee offer the right level of control. Or maybe I'm using it wrong.You also have to be careful with these because they can burst a tube of caulk pretty easily. My first attempt with the Milwaukee blew out the back of the tube and required extensive clean up. 😃
Yes you are using them wrong.
I have the original old style ryobi tube. I have used it as you said fur adhesive. But I have also used it for running beads on kitchen counters, bathtubs, windowsill and more.
For best success and bead sizes, it started with the size of the homm
hole you cut on the caulking tube. Followed by the speed of the gun. For small beads you Must use the lowest setting/speed and then work your way up the speed to fit your need.
For construction adhesive you can start with a big hole cut at the yip and a more aggressive speed.

However the only time I blew a tube was when using construction adhesive or had the setting too high/fast for the tip hole size.
Once you master the right tip size vs speed, no more blown tunes.

Tip: I wrap the gun trigger and handle with saran wrap. When it get too messy from handling, i replace with a new saran wrap.

As another reviewer noted, these types of models are very helpful for construction adhesive, where you might be going through 10-20 tubes per day. Otherwise they aren't as helpful for small jobs, and also hard to fine tune for basic detail oriented caulking (tiles, floorboards etc).
Yeah, its hard to get a machine to match finessing a project. Even when I was gluing a stone retaining wall together I don't think I used 10-20 tubes in a day.

SZOOFIM2 still seems to work. Sometimes I need to click Apply a couple of times and refresh for Amazon to accept codes

I'm currently replacing caulk at brick expansion joints on a 24 year old house. I did 2 of the joints today and that took 3 tubes of NP1 type caulk. Manually squeezing a standard caulk gun was tougher than chiseling out the old caulk. I have 2 joints to go, so I'm in for 1.

You'd never have the control you need for precise jobs....

Now you can run crappy caulk lines faster and easier!
Mine were going to be crappy anyway, so at least they will be faster and easier!

Darn - Can't get the code to work, and I have been looking for one of these. Refreshed, cleared cookies, tried like 5 times. Oh well.
