Has this ML150 been software upgraded to fix the 1024 week roll-over
problem, and has the lithium battery defect been corrected ???

The ML150 did not have a rollover problem. The lithium battery problem
modification has been completed by a ex factory authorized warranty/service
station in Maryland. The fix now allows the memory battery to last the 10
years it was supposed to. I have the receipt for the mod and will guarantee the
unit is working perfectly.
