"There is no different in the 2 except branding only". The sales person is arrogant if he think Joven is same as Grundfos since he described as "no different".

Grundfos is a multi-billion euro dollar company who provide not only water pump for residential but also for heavy industry. Joven is a multi-million RM local company and only produce residential water heater and pump only.

It is same logic where Applx Iphxne vs Ninetolxry (Msia local brand), both also can call in and out, surf internet, whatsapp etc. But the brand, quality, furnishing and spec are different.
