Review: Good gun - Bought this to reach some areas in the eaves of my house off of a scaffold. It did a good job. For what it is, it's pricey, but it is a quality product that will last a lifetime for sure. You do have to buy the adapter if you want to use standard 10oz caulk tubes, which is annoying. For the price I feel like that should be included in the package. Just something to be aware of.
Review: Outstanding Tool. - This is a well made tool. It is heavy duty and just the tool I needed. I have some very large windows over 6 feet tall with brick facia that are over 16 feet above the ground to the base of the windows. I quickly modified this tool by swapping out the pusher plate with one for a 10 Oz cartridge. The screw thread on the push rod is 1/4 - 24, so if you can plan ahead of time, you can get the appropriate sized nuts to adapt it. I used two pieces of duct tape to secure the 10 Oz. Pusher plate. A piece of duct tape will also hold the cartridge in the larger carrier. I would suggest an extended nozzle for an even better job to address the thickness of the larger carrier. New Norn does sell an adapter for the 10 Oz cartridges that I am sure is equally well made. I was looking for the maximum of reach and reduced weight for my needs. I finished my tasks in under two hours. Outstanding tool! Big problem solver for a DIY guy.

### ⭐⭐⭐⭐⭐ Good gun
*by A***W on October 17, 2024*

Bought this to reach some areas in the eaves of my house off of a scaffold. It did a good job. For what it is, it's pricey, but it is a quality product that will last a lifetime for sure.

### ⭐⭐⭐⭐⭐ Outstanding Tool.
*by H***E on March 5, 2024*

This is a well made tool. It is heavy duty and just the tool I needed. I have some very large windows over 6 feet tall with brick facia that are over 16 feet above the ground to the base of the windows. I quickly modified this tool by swapping out the pusher plate with one for a 10 Oz cartridge. The screw thread on the push rod is 1/4 - 24, so if you can plan ahead of time, you can get the appropriate sized nuts to adapt it. I used two pieces of duct tape to secure the 10 Oz. Pusher plate.

### ⭐⭐⭐⭐⭐ Well Built and The Most Ridiculously Long
*by M***L on January 28, 2026*

I picked this up to solve a very specific use case: Pigeons. I needed to precisely apply bead of bird repellent goop on the edge of a gutter, 4 feet under the edge of a railing, 35 feet in the air. I didn’t want to mess with ladders or otherwise break myself in half. This wacky, niche caulk gun did the trick. Other benefits is building goodwill with your neighbors, who surely don’t have one of these wacky caulk guns to solve the same bird problem, and as a conversation piece for other DIY’ers who have no reason to own such a device. The downside is that it’s expensive and if you want to use a standard 10oz caulk canister, you need to also purchase the Newborn BRP-10 accessory.
