Sorry,at this stage ,a rush to judgement is unhelpful and I cannot agree with your present stance.All I can tell you is to repeat what I have already posted.I have had contact with such samples and have been impressed....but they are what they are...samples and just that...one step along the road to eventual production. By implication,you expect a product which is to a subscription standard rather than something marketed within budget limitations.If that is what you expect,then you must find another route to your goal.
If you have invested your own capital into the development of a model,then you have every right to question its progress on the basis of mutual trust..otherwise you,like the rest of us,can only make our ultimate judgement in a purchase....or not.
For myself, it's a must...a pannier and auto train my route to school and a way down the valley to Abercynon and the heady delights of Cardiff. I am going to enjoy this one.
