Sent them ECU off a 2009 MB E350. Circuit board had big problems, along with other things, so we went with a new rebuilt unit. Had it at my house shortly after they informed me they had one for me. O2 sensor codes (new O2 sensors) were gone and now I can actually figure out why the engine misfire codes. Couldn't get to the root of the cause before. Excellent company to deal with. Very prompt with updates.
