mr eco,

here's a very simple way to put this matter to rest. tell your mr alegre to offer a SIX MONTH RETURN WARRANTY. kung sa akin lang, i'd take you up on your offer eh (6km/L lang mileage ko on my gas guzzler). pero hindi ako magbibitiw ng 6000 pesos on the basis of your claims.

If your mr alegre is THAT confident of the functionality of his device, he SHOULD be willing to offer a money-back guarantee. kasi pag wala yun, we just have to believe you and plunk down our 6000. malaki-laki na rin yun, mahirap na buhay ngayon.

seriously --- i could REALLY use a gas-saving device. kahit siguro 1 month return lang, bibilin ko na. What say you and mr alegre?
