Easy to use and feel confident using it.

Prefer my older model!

I have some difficulty with this new model. Firstly it is sometimes hard to blow a sample as the flow doesnt always work. Secondly when it does the sample size seems very small I therefore don't feel confident on the accuracy. Quite disappointing.

Hi John,

Thank you for your feedback. We regret to hear you're having difficulties with your new unit.

The sample size issue should not be an issue - sample size does not affect the reading since the device itself determines how much sample is needed. It does so by double clicking/beeping once enough sample size have been collected.

As for the flow issue you're facing with your unit, we will be sending you an e-mail separately to ask for more details in order to assist you better.

alcosense Zenith

Great unit no doubt but cover over batteries is difficult to remove. Fearing breaking retention lugs and finger nails etc. Apart from that all good.


very happy with alcosense small easy to use quick glad i made the change

Don’t leave home without this.

I received this new model last week and I have used it often since. I attend a lot of functions as a Rotary President and, although not a heavy drinker, it is easy to lose count. My highest reading was 0.048, but I was not the driver.

Richard's Review

I have not seen them yet, can you please tell me where you sent them

Hi Richard, So sorry for the late reply. I believe one of our customer service agents would have reached out to you after you wrote the review. As you purchased a trade-in, they do take longer to process as we wait for your unit to return to us first before we send out the new unit. From what I can see in our system, your 2 trade-in units have already been shipped out in June and July this year. Please contact us if you have not received them.
We have only used it

We have only used it a couple of times, but seems very reliable.
