RD900 Breathalyzer - Rechargeable

Good quality. if drinking beer and measure it straight away it will show crazy results like 2%. after that need to wait until it dries. otherwise sober person will show 0.4%. so don’t know about accuracy. be careful. might be good to measure on the morning after a good sleep.

They come very well packaged, good quality, I liked them a lot.

Very practical, useful and accurate.

Very good quality and it is very easy to use and delivered today thank you.

so-so

Fully functional, it came very well protected and is super easy to use. I really liked it; it's a product that I am offering to my clients for their staff evaluations.

Arrived quickly, haven't tested it yet.

Actually works. Roughly seems accurate, but don't have anything to compare to. Came fully charged.

Excellent item as described, fast shipment, i reccomend this seller.

Works very good, only thing is that above 1.92 doesnt measure. I like, looks professional and good quality

That seems correct to me, it's a pity that everything is written in a foreign language and not in French.
