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.

I can’t believe you can buy this online. Must have to work on controls. Great

For the price, this can't be beat. It won't come with a manual.

Perfect price perfect tool will buy again

Funciona en los elevadores Otis, contiene 65,500 sesiones y los materiales se parecen mucho a los originales
