我们的产品不能完全说最好，也绝非嫁不出去的姑娘。求翻译！

We can not say our products are the best; but they are not what nobody wants either.

气话来的吧？
这话最好不要说，
作销售不管对方怎么样，我们都要有耐心
即使对方很不是东西，我们也不能让他们坏了我们的习惯，我是说说话礼貌的习惯，无视好了
如果还想继续洽谈下去，可以这么说：我们的产品不敢说最好，但是也有他的优点，
We can not say our products are the best; but can not denied there are strongpoints either。
下面可以接着解释了

We cannot say our product is the best. But it is not a girl that nobody wants to marry, either.

Our products can not be said that the best, it is not out of the girls do not marry.

四楼说的对哦,顶下,生意不成,仁义在,至少还有下一次,至少大家还可以做朋友的挖!!呵呵~~~
