I was not expecting it to come with a case. It has a case and batteries. It is very accurate and quick to use. I can use it over my nail polish as well. I wanted a back up in the house with everything going on out there and this was perfect. It is important to have one with Asthma and with Covid. There are so many out there but this was a perfect choice. I love the colors. It was well packaged and it shipped quickly. I give this seller two thumbs up. ### ⭐⭐⭐⭐⭐ It works great! *by K***G on January 10, 2026* Great product to have! ### ⭐⭐⭐⭐⭐ Peace of mind. *by J***S on March 20, 2022* I was advised by my brother who works in healthcare to get a pulse ox immediately when I was diagnosed with COVID-19. He told me the ranges of healthy versus not healthy and talk to your doctor to you need to go to the ER ASAP ranges. I was taking my pulse ox in the morning afternoon and at night during the time I had COVID-19. Thankfully I recovered, but having this little meter which I take everywhere is peace of mind. What’s nice is it has a lanyard on it so you could wear it on your person. It’s super easy to use and I love the fact that you can change the display. So if you have it hanging around your neck you can look at it looking down when you get a reading versus if it’s in another position it’s super great. Knowing how much oxygen levels are in your bloodstream is important. And this little meter is quite affordable for peace of mind. ## Frequently Bought Together - mibest OLED Finger Pulse Oximeter, O2 Meter, Dual Color White/Pink - No-Touch Thermometer for Adults and Kids, Digital Accurate Baby Thermometer with Fever Alarm, 1 Second Fast Result, FSA HSA Eligible, Easy to use, 2 in 1 Mode - Ever Ready First Aid Fully Automatic Blood Pressure Wrist Cuff Watch Wearable Monitor for Home Use - Pink- Batteries Included --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/150272416-cn340-series-oled-pulse-oximeter](https://www.desertcart.hk/products/150272416-cn340-series-oled-pulse-oximeter) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-05-18*
