The goods (Alcohol tester GTX Protector) were received on 27 January and sent back on 8 February, i.e. on the 12th day after receipt. The withdrawal from the contract was made within the statutory period pursuant to § 1829 para. 1 of Act No. 89/2012 Coll., Civil Code. The time limit is preserved under § 1831 at the moment of dispatch. Your protocol states: visible mechanical damage: NO undelivered accessories: mouthpieces 5 pcs Please note that in the case of withdrawal within 14 days, this is not a complaint of a defect, but the exercise of the consumer's legal right. Therefore, the performance of a "diagnosis" is not a condition for the acceptance of a withdrawal. According to § 1833 of the Civil Code, the consumer is only liable for the reduction in the value of the goods resulting from handling beyond what is necessary to become familiar with the product. The law allows for a reasonable reduction in the amount refunded, not a rejection of the withdrawal as such.

The device can be switched on, but its measuring capabilities are zero. Tested 3 hours after alcohol consumption and the result was 0.00 ‰. Since there was alcohol in the blood, I consider the product to be non-functional.
After inserting the batteries, it can be switched on
The instrument measures zero.

Verified purchase - review from a price comparison website
functional, does not need to blow as much as the Sencor
seems to measure more consistently (and less) than the Sencor, so all the better
AAA battery, too bad it is not normally with charging

It measures really great, I tried several tests in a row and the deviations were minimal. For how cheap it is, it surprised a lot.

The new device looked promising, the measurement was very fast, however, the measured values for residual alcohol showed zero, where you already have almost 1 per mille (several beers, some drinks, a time gap of half an hour before the measurement), the device shows 0.3 once, 0.45 the second time, 0.25 the third time. Sent for calibration of the manufacturer, where according to the protocol the values were ok, after calibration supposedly adjusted and adjusted. The result is that the device behaves exactly the same. The old device shows much better readings than this one, even though the readings may be inaccurate, but it is more reliable than this device. I was wrong.
Measurements are highly indicative and actually useless
shows a different value each time
unusable for residual alcohol detection
