All the quotes above are from Grasshopper thread. (yes, quoting myself ,too).
I thought maybe addressing the topic might be done over here in the languishing Hopper Warranty discussion thread?
The topic being, How many Grasshoppers have "stopped working" for you?
A couple of parameters might be set and I can suggest one or two but I'm an admittedly poor statistician, so I encourage other input.
I hope this doesn't devolve into negativity or complaint department-level stuff; that really is not my interest. I have a much more detached-observer, academic perspective. Just looking for some data and/or some anecdotes to go along with it.
@Al.. has had an impressive number of broken Hoppers and we know others have, while we also recognize the limitations of our data, so
we can't say that there are not hundreds or thousands of trouble-free units in use. I think there are! Further, I emphasize that the improvements to design/dependability are ongoing, so this is constantly shifting ground anyway. 'Reliability' of a Hopper made today will not be the same as one made 6, 12 or 18 months ago.
Back to some guidelines.
We can count, as
@Al.. puts it, number of Hoppers that stop working; I like the phrase, but might refine it as, 'the number of hoppers that have required replacement or factory repair of either the Back End or the Body. Leave batteries, external charge cables and front end mouthpieces out of this picture.
A codicil to that would be if a Hopper had both Back End and Body replaced at the same time, this could count as two repairs. I justify this because it happened to me, of course!...and they were separate issues.
The count should not include the last one in hand, the presumably now-working Hopper; only the number that have required repair/replacement. For me this is a matter of counting the number of separate warranty claims I've created, plus one because of the double repair I mentioned above.
My last thought on metric is that the count should then be divided by the number of Hoppers one purchased for the counting instance in study.
I purchased and will account here for 4 Grasshoppers. (received early Aug. '16).My warranty list has 8 distinct claims, but one is that double whammy, so I count 9 'broken hoppers'. These are from two of the Hoppers that I kept. The two that I gave to family 'broke' very early on, will need Body's, just have not been returned yet. Because the family will be leaving it to me to do their returns for them, their Hoppers are counting as mine for this purpose. This make 9 + 2 = 11.
Now I divide the 11 'broken' by the 4 purchased and come up with a rating of 2.75 breaks per hopper (bph).
If I don't count the two I gave away, my bph is 9/2, or 4.5.
Someone please tell me you have a bph equal to or higher than mine so I don't feel lonely here in the stratosphere of numbers! Oh, wait, I said I wasn't attached...
We would also surely like to hear from those folk's who have longer term success stories! but then again, why would they even be aware of the Ethics, Karma and Grasshopper Warranty Discussion?
