I'd pay a bit more and buy this one:

for the reasons outlined in the links above.
For example:
"Also, important note about adapters with mechanical HS/MS switch: in addition to the fact it is not very convenient to switch it manually, it may be not possible to perform some operations with this type of adapter. If some operation requires a simultaneous access to both HS and MS (so FORScan needs to access some module(s) on HS
CAN bus and, at the same time, other modules on MS-
CAN bus), it cannot be normally executed using adapters with mechanical switch. Example: reading parameters (PIDs) in virtual module All, Module initialization subfunction in service functions "Remote keyless entry and Start"."
I think "virtual module All" refers to the Forscan feature of selecting multiple modules to display at once,
rather than having to select and view just one module at a time.
