his is something that plagues Chinese manufacturing still. I know from others like Wai Won Ching of eZeebike and David Miall of Wisper that any manufacturer or supplier needs to watch production standards all the time and never take an eye off the ball to prevent things slipping.
Only a couple of days ago I heard a Chinese manufacturer openly admitting how far short they were of the Japanese in this respect. That admission is something that would never have occurred not long ago, given the long term enmity of those two nations. However, the admission and the fact he said they would get there does hold out hope for the future, but that's little consolation to you at present.
yes, there are major problems with money (i.e the budgets the clients provide for the project) and the exact same human attitudes towards industrial relations / bosses vs workers we had when manufacturing was in England or Europe.
The Chinese had a similar discussion in Singapore a couple of years ago about this issue...
I think there is a big cultural difference even in the Orient - Japan and Singapore are very strict about quality and discipline in work whilst the Chinese are more like the British in the "good" old days, with at best case a "good enough" culture, at worst case not caring as long as they get their pay packet!
A powacycle Salisbury new is now nearly £800, so I think the competitors will be fast barking at their heels (for instance the Scottish Alien Gents Special looks like a significant competitor especially now the chap has expanded his customer service resources).
It could of course also mean that Powacycle are selling loads of units and feel they can afford to tolerate a few lemons and even lose customers to keep up volume - I will be looking at their next set of financial results with interest...
