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.

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 *by G***L on 19 February 2025* The 377 Newborn Caulk Gun X-Tender is a high-quality tool designed for precise and efficient caulking applications. Featuring a durable construction and smooth trigger action, it ensures controlled dispensing for professional-looking results. The X-Tender design allows for extended reach, making it ideal for tight or hard-to-reach areas. Built for ease of use, it provides consistent pressure to reduce hand fatigue and improve accuracy. Whether for home improvement or professional projects, users appreciate its sturdy build, smooth operation, and enhanced reach, making it a reliable choice for sealing and finishing tasks. ### ⭐⭐⭐⭐⭐ Review *by H***E on 5 March 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. 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. ## Frequently Bought Together - 377 Newborn Caulk Gun, X-Tender, Deluxe, 45 in, 29 oz., Gray - HAMUULL 3 PACK Caulking Nozzle Extension Tube，caulking extension nozzle,caulking gun extension nozzle,caulk tube extension --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/290945371-newborn-377-caulk-gun-gray-29-oz](https://www.desertcart.be/products/290945371-newborn-377-caulk-gun-gray-29-oz) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-22*
