Great Portable Device

I wanted to thank all of the staff, great job. I wasn’t aware that I would receive all the international outlet plugs with the Breath Smart! After unpacking and allowing it to fully charge i realized what great quality this little device is. Your packing was excellent and It has been working perfectly. I love the fact that it’s so portable and holds a good charge. I’ll update after using it for a few more weeks. As I said before I’m very impressed thus far.

Great gift for cyclists!

I bought one for my bike-mad boyfriend as a Birthday present and he is so pleased with it! He has been using it on his weekend trips and on his occasional commute in to his office recently. He has found it easy to use and read while he is on the move. His mates ask him about the readings when they ride together! I’m so happy I found this as both a stylish and useful gift!

Awesome monitor.

I have used this little monitor extensively over the last few weeks both outside and indoors and overall I cant fault it! Its super lightweight and the battery lasts really well and charges quickly. Its small enough to look discrete on my rucksack and its very easy to read and understand. Having spent so much time in the house during lockdown I was concerned about the air quality in my London home. It turns out that the current air quality is better than I thought overall but definitely peaks on bad days and when we cook and forget to open the windows. I have been avoiding most public transport recently but on the few bus journeys I have made the monitor has gone straight up to red. The monitor has helped me to identify the dirtiest roads nearby and I now avoid them on my walks.
