Got one a couple of years ago, seemed to good to be true. All those tools wrapped up in one for $2200. Ordered one and waited and waited. Thought I got scammed. then it came. Laptop,cables and case. Tried it and it works. you have to figure out what cables to use, but it works. seems to be a copy of TKE tablet. Really no support on it. Has all the big four plus. the web site was Elevator Service Tool. It comes and goes. Ebay had one similar to it. That one also worked.A coworker got that one. So that is my experience. May the force be with you.
