My last MMM failure took out a $100 lipo with it. The MMM burned to the ground. There was only a little melted shrink wrap on the lipo but when I stick it on the charger it is dead as a door nail.
I think the MMM's pricing for the masses has forced CC to lower quality, I would rather pay 3-400 for a unstoppable controler or 60 for a perfect bec, but unlike castle, I could care less if brushless goes mainstream.
well i for one will gladly send mine back and pay a little extra to have it updated and fixed for good if thats what it takes to get a reliable MMM....like you say i would rather they charge more and put out a better quality unit
