Pros: Not certain how accurate it is, but seems fine. Definitely shows presence or absence of alcohol. Can test by blowing over a bottle of rubbing alcohol if you don't drink. Will show alcohol if you wipe rubbing alcohol across your face and blow or if you swish mouthwash and blow.

Overall Review: Yes... not certain on exact accuracy so just don't drive under influence.

Pros: Does perfect disk to disk copies in independent mode including HD to SSD. Works well as a drive hub.

Overall Review: Yes

Pros: Its well priced very good RAM. Works flawlessly. Even came with the metal sticker plate to decorate your PC with beside the GPU and CPU metal stickers if you are into that sort of thing.

Overall Review: yes

Pros: Washable and reusable while giving n95 protection. Purchased for my parents who are almost 80 years old.

Cons: Delivery was slow but understandable given covid-19.

Overall Review: If you are in a vulnerable group these are great as long as you follow self isolation as much as possible. Social distance with these on for protection. They are comfortable and fit well. Very nice that they are reusable and washable.
