I have been following this thread with great interest, but I have to say I share the scepticism raised by some other members. The original review says Eco vs H50 however we only see pictures of the Eco with no real evidence and then just a summary stating the Eco is substantially better.
Picture and information about the H50 can be added if you would like? I originally didn't include them because there are a number of other reviews out there of the H50 and very few of the ECO .
