hi bro,
sorry if have any offend, the Petit filtration system is very expensive due to the rental for 5 years which mean RM 6600 may i know how was the penalty if i terminate the contract b4 the contract end..and what service provided in these 5 years. what abt after 5 years? what service charges need to pay for it and the filter replacement charge how much. please list everything clearly for protecting consumer like me. 
i interesting with this product but when i face to face ask those agents, they seems like hidden something. i very fed up with those "selling technique".
