You can check the 'GHB' in the drink within 1 minute. This product is a sticker type and can be used anywhere, such as a cell phone or wallet. So it is easy to carry and can be used secretly without being noticed by others. The “New G-Check” has been upgraded to be less affected by an external contamination by the protective film, and thus more accurate results can be achieved. The color change can be easily checked by comparing to the reference spot color. It can accurately detect GHB in various beverages. The pattern on the product may be mistaken for a scratch, but it is a characteristic of the paper.
