    • It’s low cost and can give you valuable life saving information.
I have to start out saying that I am a telemetry RN. I always have extra pulse oximeters with me to give out to elderly people I come across in my personal life. These are so small, portable and versatile. When I am going patient teaching at work, I am finding out that most people don’t know how to check their own heart rate to make sure it’s safe to take their heart medication at home. You can use them during your workouts to check your heart rate. For physical therapy to see how well someone is tolerating the activity. Great for this pandemic we are having for when someone is tested positive and needs to check oxygen levels to know when to go to the ER. And anyone with asthma, emphysema should have one. Also anyone with heart issues and on medication to control the heart rhythm. I have notice that people are wanting to get their elderly family members Apple watches just for the EKG aspect. The Apple EKG component is very limited and not a true EKG. You mostly need to know if the heart rate is irregular, too fast, or too slow . This pulse oximeter can do the same thing for pennies to the dollar of the Apple Watch that costs hundreds of dollars. Plus, most of the older generation is not going to learn how to use the Apple Watch. Get this instead. ... show more

    • Peace of Mind
This was very inexpensive compared to the others listed on Amazon. I bought this when my husband caught covid. I suspect my son and I have it too so I thought it would give us some peace of mind. We haven’t had it for very long so I can’t speak to how long it will last but I love that it came with batteries and it was very easy to use. The readings seem accurate and in line with readings from the doctor. I didn’t notice when I purchased it but it even came with a lanyard. I was trying to find one around the house when I noticed it in the carrying case. I’m very happy with my purchase and recommend. Even if it doesn’t last very long it is worth the $15 while we are sick! ... show more
