It will work without a mouthpiece but everyone is going to want to use it and know their BAC, it's nice to be able to swap out mouthpieces

As a party host its nice to have extra, clean mouthpieces so you know the people leaving are under the legal limit.

Great for when chilling with friends and wanna make sure everyone is safe to drive

Don’t have much to compare them too, but I find them fine no issues

I wish it was cheaper but for the cost it’s okay.

The BACtrack is simple to use and is a good tool for your tool box.

Perfect fit. Nice to have extras for others if needed.

Very compact and enough to last for quite some time.

Great necessary product. Bought this for my 21 year old daughter to keep in her car. She is not a big drinker but I think she would even use this with friends in the event they wanted to drive after having a few drinks. You never know.

Good value here for using your device in a group setting. There are enough to with up to 10 friends and family. I highly recommend adding a pack or two when you buy the BACtrack unit to save on shipping. Perfect fit. 5 stars.

We love the fact that we can use clean mouth pieces prior to use or passing the machine around. More peace of mind.

Bought the extra mouth pieces so we could share with friends!! Totally worth it. They all want to try it and we’re not spreading too many germs.

The 100-pack of the C-series mouthpieces is the best buy if you use mouthpieces with your device.

When testing multiple people for their BAC, the mouth pieces work great

The C6 can be operated without a mouthpiece. I only bought these to use when sharing my C6 with others.

With the extra mouthpieces you can feel confident in letting others try it out without worrying of any cross contamination

I'm glad I bought the big pack because as soon as my C8 comes out everybody wants to try it!

They are small in size so you can easily fit some of them into the carrying case that can be purchased seperately. It's always good to have a few spares on hand in case you lose one.
