    Re: Rate of failure Polls

    Ok the 6900 has a poor track record (probably a lemon) and we all know that but if 3 out of 20 coffee snobs complain about the 6910 or the silvia then what can we learn from that? Are they bad or are those 3 complaints isolated incidences. Is this anecdotal evidence to indicate bad products? What about 3 in a 100? Its impossible to tell! Like you said I will be more entertained by the poll rather than finding out anything useful I can pass on to perspective buyers. Anecdotally (my gut feeling - not using science anymore) is that the silvia is reliable and the 6910 probably is but its too early to call. I promise not to give anyone a stats lesson! ;D

    Its often the anectodal which hold more truth (alla lies, damned lies and statistics) than statistics.

    The most powerful form of advertising, word of mouth, is based on anectodes, not carefully digested stats.

    As I say, forget the science or lack thereof of the poll, use it as a ballpark guide, and be entertained.

    And Ill do just that!

    The silvia is not well known by the general public.
    CS are not the general public.

    The poll is of a certain demographic - coffee snobs.

    Some CS own EMs, some own Silvias.
    So how is the poll useless?
    I agree the sample is small but as 2mcm said, the "anecdotal evidence probably means something".

    I think the fact that Sunbeam have replaced failing EM6900s with the new EM6910 says it all.  It would be nice to get the real stats from Sunbeam though... Im sure they are kept in a vault guarded by robotic sentries with high powered laser weapons designed to incapacitate armoured vehicles.
    You never know - if the robotic sentries are version 1, they might fail when used a few times.  :P
    or Sunbeam put more R&D into the robot sentries than the machines.... Whos willing to test this?

    Re: Rate of failure Polls

    Other than just the failure rate is the general public perception of different machines and their longevity/reliability.....

    Using Evilbay as a reference

    A Gaggia Classic 3 1/2 years old in "good condition" fetched 43% of new value...

    A "barely used" Cafe Series Sunbeam 6 months old in "as new" condition fetched 28% of new value.....

    Silvias dont appear on Evilbay.... (Read what you want into that) but on CoffeeSnobs they fetch up to 75% of new price...

    Whilst Evilbay isnt the best of reference sites :, it does indicate how the market perceives the relative merit and longevity of machines from different manufacturers.... using a large number of perspective buyers.......

    As for the poll on the EM6910 vs Silvia, I agree with our statistician that it is meaningless. It would be nice to get the real stats from Sunbeam though... Im sure they are kept in a vault guarded by robotic sentries with high powered laser weapons designed to incapacitate armoured vehicles.

    Re: Rate of failure Polls

    Yes and no IMHO.....people generally gripe when something breaks....and there has been a whole lot of gripe about the 6900 both here and on CG....and the 6900 doesnt even go to the US....

    Based on the seatofthepantsometer, there is no doubt that a whole heap of 6900s broke...I doubt that anyone in Oz is on Silvia number 3 or 4....There are stories of Sunbeam owners with many replacements.
    Perhaps, there are more Sunbeams in Australia than Silvias but Id be surprised. The Silvia has been on the market for 10 years. Despite the limited sample, this anecdotal evidence probably means something....

    Here, every Silvia of Sunbeam owner who does not access the internet is automatically eliminated from the sample. Every Silvia or Sunbeam owner who does not access the Coffeesnobs site, ditto.

    What the poll shows -- is the percentage of failures among owners who voted. You would have to have a a volume of data such as sales volumes to weigh the sample accordingly... out of the polls scope, of course.

    Still, as an indicative ball-park figure, the exercise and finding are interesting to say the least.

    I am a mathematician/statistician and this poll is useless. Sample space is way too small, biased and skewed. The only meaningful poll would be to contact Sunbeam and Rancilio direct.

    Good for entertainment value.

    Why not use a hard drive recorder that can also read/write dvds?  :P

    Im confident Javaphile does not intend his poll to be definitive --but rather, indicative.

    With professionally conducted polls, there is an inherent degree of sampling error to start with, around plus or minus 2 per cent.

    Here, every Silvia of Sunbeam owner who does not access the internet is automatically eliminated from the sample. Every Silvia or Sunbeam owner who does not access the Coffeesnobs site, ditto.

    why do you say you expect a significant increase in the rate of failure of the EM6910 - is it all the electronics?
    They have only been out a couple of months and they already have a failure rate approaching 20%. They have 6 times as much use yet to go before theyll have been in service for a full year. The number of failures can only go up from here unless something is changed on the design/build end.

    Silvias have been around for many years and as such the rate of failure shown can be said to be fairly representative of a full year of service, not just a couple of months.

    are you posting the actual votes for the Silvia poll Java - its not up yet
    The polls have been opened in that as soon as you vote you can see the results. But you have to vote to see the results. Hence the third option in all the polls "I dont own one, I just want to see the results!".
