osmio4K+ experience

[lme]

After playing with this new box, my first impression is that it is not as advertised "the only box in North America witch can scan transponders 3° apart".
Did some scan tests with this new box & my old Vu+04k, and as you can see from the pics osmio is far behind:
Using TNAP4.1, scan tests were done on different satellites trying to build up my channel list.
the worst example of all is on 101W with 7 tps at 4° apart out of 17, where osmio failed miserable not finding all tps:
[Only registered and activated users can see links. ] [Only registered and activated users can see links. ] [Only registered and activated users can see links. ]
and here is the scan result done by Vu+:
[Only registered and activated users can see links. ]

This is happening on some other satellites. openvix image on osmio did a better job, but not as Vu+ with openvix img.
Another issue I have with osmio is that it has hard time to clear some channels where Vu+ has no problems.

So, my conclusion is:
1-maybe i use a wrong scanning procedure;
2-the tuner is not up to as being advertised; or
3-the QC of the manufacturer doesn't do a good job on checking the final product, and I ended up buying a door stop.
any suggestions ?
