Value for money!

I am planning to buy a RO based water purifier so purchased this to measure TDS. Product was delivered on time. Comes with a black case. Doesn't have a display with backlight. I have tested this device with water from different sources. Below are the results.
Distilled water - 10 PPM, was expecting it to be zero.
Rain water - 30 PPM
Water from Ganges - 90 PPM
Tap water - 300 PPM
Water with a pinch of salt - TDS was too high to measure, the meter went blank :-))
