Does anyone use a water saver kit with their RO/DI unit?

[BlastoLove]

Sould I get the BRS water saver kit with the 75 gpd 5 stage RO/DI unit that I just bought, it would turn the gpd into 150 gpd and cut the waste in half. Do you have one or know someone that has one and could you tell me whether or not it is the best option in the long run???

i have one because it lets me make more water faster and it says less waste
