Save your money. *by A***T on Reviewed in the United States on September 14, 2019* Tested it after different meals and it was inconsistent and wrong. I ate a bunch of stuff that would have definitely knocked me or if ketosis and it still said I was in ketosis. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Love it *by M***O on Reviewed in the United States on July 25, 2019* Been using it close to a week now, near the start of a keto-diet. While I can't attest to the accuracy of the device (how closely it's measurements match a "gold standard" reference test), I can tell you the precision (how tightly grouped are several measurements taken with this device) is fantastic. I can report the same observations as others, which is that breathing into the device at the start of the exhale will give lower readings than breathing into the device near the end of a breath. Others have stated that using breath near the end of your breath more closely matches blood readings, so this is what I've been doing. That is, breathing into the device when my lungs are nearly empty. The precision of several readings is awesome! And you can watch the ketone levels rise as a day of fasting progresses. I love this device. Had no idea a breathalyzer could work so well for ketones. Definitely worth the money. ### ⭐⭐⭐ 3.0 out of 5 stars Readings seem erratic so far! *by C***K on Reviewed in the United States on July 13, 2019* I just received it today (7/12/19) and my readings have been all over the place... from .2 to 2.5. Not sure if I am doing something wrong so I am going to give it a few more days and compare the results to my urine test strips and see if it becomes more accurate! I will post an update in a few days! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/129233138-ketone-monitor-device-testing-breath-ketone-content-with-32-recent](https://www.desertcart.sg/products/129233138-ketone-monitor-device-testing-breath-ketone-content-with-32-recent) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-24*
