Review on 🔋 Dianamix Cordless Lithium Battery Cartridges for Enhanced Compatibility by Noah Lewis

This caulking gun is a Chinese copy called DadaoMix of the original DianaMix tool. The picture is misleading and does not show the Chinese logo. The original tool had the feature I was looking for - smooth control of full piston speed from 0-100%. I bought and tested a gun. Unfortunately, it only worked properly for a few minutes and then broke down - it lost speed control and retreat and just started running at full speed. I requested a replacement and Revain shipped the replacement unit quickly. To my surprise, the same error reappeared after a few minutes. It is obvious that the electronic controls of these tools are not well made. After I returned the second gun, Revain refunded me and bought a Makita stamping gun. More expensive but works like a charm :)
