This is a good product to give you a heads up. I wouldn’t put its accuracy up against a police officers breathalyzer but it will give you somewhat of an idea.

This is fine for checking ones consumption before leaving the pub to head home. If you are trying to check a family member who has a drinking problem it is better to get the upgrade. I did and opted for the S80

I bought this just out of curiosity, kinda as a toy. It will give 3 different BAC levels, back to back. Definitely a novelty item, not something that can be trusted for an accurate reading.

After 4 uses it needed recalibrated. Saying the user was drunk when they were completely sober. Only way to recalibrate it, is to send it to the manufacturer's office in SanFrancisco for I think it was $28.00 plus shipping cost. So I spent $60.00 for the unit that failed after 4 uses and I am supposed to spend an extra roughly $50.00 to repair. Nope, don't think so. I returned the unit and got my money back.

Probably the most annoying thing about this device is that it is hit and miss on connecting to the phone, sometimes it works great, other times it will not connect at all.

For the most part it's pretty accurate, or so it seems. But there have been times I have tested it when I wasn't drinking at all and it still said I was. So I'm really not sure how accurate it is 100% of the time. It's a good concept, but needs some work.

Certainly will help when properly used.
My concern however is when one can go to the app and see where the "drunk people"are.
Could lead to abuse in my opinion if user attempt to compete.

Great device to own to prevent getting an OUI... it's quite accurate for a small Bluetooth device... I'd recommend it to anyone who's looking to protect themselves from getting an OUI

We got this for our trip to Scottland, lots of scotch drinking. We had a great time using it and it's easy to use. Feel like it helped to judge if driving was ok or if we needed to wait a little bit.

The device is pretty accurate it does require a few reboots every now and then. I expected that because of the size of the device. I would definitely purchase another one if I ever needed to.

Don't know how accurate it is but it's fun and if it even is close to accurate as they say it is in the manual then it's a good thing to have on a night out
