Hello I can give you my honest opinion  but keep in mind i live in usa  there is no astra vehicles here also I have the 905  about 2 month ago I sold my 708  the difference between the 708 and maxisys well I think it speaks for it self is day and night  the maxisys  does everything the tech2 does and much more  I own a tech2 and mdi  I speak from my own experience not something i heard or seen on the internet  now like i said i dont know about the gm vehicles in your country but in usa it kick ass and is not even completed yet  this is my honest and personal opinion

 Hi, I fully agree with ede65. We had the 708 as a shop tool with autoboss and Genisys OTC EVO. We tryed out a new 908 and the next week I ordered one for my own self. The shop owner ordered two 908 pros for the shop. I understand the scan tool is a work in progress but still kicks the other ones around. I would not give up my Maxisys 908 for any scan tool I have used before. We are in the USA to at a small shop with body shop.

Definitely agree maxisys kicks butt and the 708 although a decent tool ain't got nothing on the maxisys. The maxisys is worth its weight In gold and getting better. Waiting for the scope hopefully soon
