Seems Obdstar x300dp plus will win ??
FYI, actually they are 2 different machines to do 2 different things.
you can regard londsor as a Key Programming Tool (esp. volvo immo), while x300 works good in diagnostics and programming and special functions(incl. odometer correction)
Lonsdor highlights its VOLVO key adding. Both the Obdstar and Lonsdor key tools work good in car key programming though.
Obdstar works perfect in full-system diagnostics, odometer correction and special functions.
