Diagnostic unit for more than one car

[Lanby]

I've been considering purchasing a diagnostic tool as we have an L320 RRS and an L322 RR and have read about the Hawkeye Total Diagnostic unit but does anybody know its limitations? or can it diagnose everything?

I've ordered a GAP iid BT, should be here tomorrow
Extra licenses are £60 but I still think it is the best option
