I have COPD, am on supplemental O2 and need to keep an eye on my sats. I've kept at least two of these around for a while now and when one recently (finally) died I replaced it with this latest and greatest version. It locks on to your vitals and starts displaying results so quickly you'll think it's a pricey institutional version. I occasionally buy one of these as a replacement or as an extra convenience, and every time they're better than the time before. If you've got an older version and are tired of waiting for it to respond, considering buying a newer version.
About 10 days the goods hung in the status ready to ship, after which the seller wrote that there was some mistake, we did not blame it all epacket, after which the seller dropped the track, that the goods are shipped. As a result, the delivery is about a month. The goods meet the requirements, the readings are accurate. I recommend the product, the seller is sociable and competent.
Being a Respiratory Therapist I've used many a pulse oximeter in my career and I was replacing one for my personal use but didn't want to pay a fortune. When I saw the price on this one, I couldn't resist buying it because the price was so low but I was pretty sure it was going to be a big let down. Wow, was I surprised... it works great and even comes with a protective gel case, batteries and even a lanyard. This was a steal for the price, I am very happy and bragging to my friends about this purchase.
Shows heart rate rhythm... oxygen rate... and heart rate itself as well.. takes 2 AAA batteries included and has a lanyard if you want that on it also... easily fits in a shirt or pants pocket though also! Very useful tool if you are tracking heart rate and/or oxygen levels... the rhythm lets you know it is accurate or what is actually making it to the finger you are clipping this too.. don't think it would work right on other appendages but works well on a finger or thumb here. Would definitely buy again! Easy to read numbers help us track oxygen rate and verify with heart rate in the night too!
When I first received this product, I immediately opened it to use for the first time. I didn't even need to reference the directions to get it going, and have used it several times since. As a person with Postural Orthostatic Tachycardia Syndrome (POTS) stemming from Ehlers-Danlos Syndrome (EDS), being able to accurately check my heart rate is invaluable. I have multiple medical appointments a week and have been able to test this product against regulated medical equipment - and it has performed perfectly! I've yet to get a reading that is different from what my nurses/doctors have gotten. This product is definitely a good buy at such a low price (less than $15 at the time of posting).
