Which MB star diagnosis is better?

I have just got one from maketrust2016 store
fastest shipping ever. very trustful guys.
they sent it with the hard drive. all you need to do is take out your hard drive and put the one that they sent. but be careful you need to have a laptop with serial port on it. i thought i can get usb to serial rs232 converter and use with it but it did not work. you need real serial port rs232 on your laptop. it means that you need old laptop. it works perfect and it really is same with the original one.
get one.
