Just installed the GX2440 on our scissor lift to replace the original charger that charged our batteries - I'm sure the GX will take very good care of our $$$ batteries. Every aspect of the product appears to be of high quality and the device is very easy to use. The only area where NOCO dropped the ball is in the transparent controls cover. Aside from the threaded design, which I don't think is the best way to go, it's nearly impossible for the white rubber grommet to stay in place, especially when mounted vertically. I know you can do better than NOCO! Otherwise great job!
