## Description

GAA21750AK3 Universal Server Elevator Blue Test Tool Unlimited Times Unlock Elevators Service Tool TT/Converter : desertcart.in: Industrial & Scientific

Review: This is the tool the OEM doesn't want you to have. With one use, it will pay for itself. I've had an older Blue Tool for years, and finally a couple of the membrane buttons gave out. But I used it a LOT. I bought four of these as replacements, and the only weakness I've spotted is that on a couple tools, the magnets on the back aren't very strong. If you know what this is and how to use it, you'll be very pleased. If you're not a qualified and licensed professional trained in the use of this tool, then leave it alone before you hurt someone.
Review: Funciona en los elevadores Otis, contiene 65,500 sesiones y los materiales se parecen mucho a los originales

*by J***B on 15 May 2023*

Tool worked fantastic first few times plugging it in. But all of a sudden the screen went funky and little black rectangles fill all the screen. I can only see the MCSS+Ocss options if I look at the screen with an extreme angle. If I look at it straight on the screen is illegible due to the black rectangles. Not sure how to fix. Technically it still works I just need to set the tool at weird angles to view the screen.
