[Elecraft] Experience with off brand Lithium AAs?

[Steven M. Knapp]

I've found a few "generic" brand Li AA's. I know the Energizer's are the 
preferred battery for the KX1, but am curious if anyone has tried these 
off-brands that seem to save a couple bucks?

For example I've had good luck with other batteryspace products:
