This is a fun product, but very in accurate readings. Usually differs around .03 within 3mins of usage. Wouldn't use for the science but more as a party trick.
No, I would not recommend this to a friend.

it's nice to have a numerical reading but the noise and time it takes to use don't make it a desirable option.
Very convenient size. Easy to get a reading. Seems to work well at times, but also clearly inaccurate at others. For example, 9 hours after last drink consumed, it gave the same reading for 3 consecutive hours. All humans remove alcohol at .016% per hour, so reading should've reduced approximately .03 during that time period.
This is a great party favor. Everyone uses it to see where they are at. Mine broke and I was sent a new one ASAP! Love this product!
I would recommend this to a friend!

I ended up sending this unit back to the manufacturer and they gave me credit for an S30. The keychain unit rarely worked and often gave an error message, even when I tried using it completely sober and following instructions.
