don't buy products from this vendor.

in 2 years ago, I did buy a 化 NO3 器, 老 sales said it does not require any external pump to inject the water ... at the end ...it is a rubbish (cost > HK$800).

i did write to this vendor and complaint the case. they agreed to replace a new motor for me ... at the end ... nothing happen at all.

so, i black-listed this vendor
