2) Tecsun has a rather questionable reputation for QC in its
initial offerings of a product. With time and experience (as
differentiated from so-called 'generations' (of which there are none
in Tecsun products), the company does improve product quality
considerably.

Actually, Gary DeBock discovered that, at least for some Tecsun products,
there are generations and that significant design changes can occur within
the same model. A good example was the analog R-9012 which has been
compared to the excellent-performing 911 but with a tuning knob instead of
a wheel. The problem is, ULDX folks started buying them in droves and many
turned out to be duds. The answer was that the good performance came from
a redesigned 2nd production run. With many recent Tecsun models that
information is hidden in small print on the inside of the carton's end
flap. When there is a difference, some of the more reliable eBay sellers
(like tqchina or anon-co) will honor requests for a specific variant
before shipping an order.
