The last service tech that worked on our elevator is excellent. He kept working until he found the problem instead of giving up on it. We avoided having the problem continue because he was diligent. The same tech is thorough and cares, your company is lucky to have him.
Customization and detailed investigation of design options by Matt. Also installation was very good.
Only thing that can be improved is time of manufacture, it took almost 3 months for the whole process which is very long.
