It required maintenance already when I got the machine. Been on the shelf for too long
Ok!
Expensive plastic box. A little unnecessary when these can be washed.
A little pricey
Typical but these can be used more often.
Very good that you can buy these mouthpieces loose.
Can't put wrong breathalyzer. Hygienic, separately in bags.
The design is good and easy to replace.
Functional and suitable for the device.
Suitable are, no complaints.
