Bought this to use at home for my daughter ,easy to use and quick enough she don’t get irritated.

Simple and bright to read. Good quality. Value for the money.We use it to check the pulse number.

I was recently diagnosed with Covid and it was recommended that I have a pulse oximeter to monitor my oxygen levels during my battle to get better. It's very easy to use and read the results and only takes a few minutes.

I recently had the chance to evaluate a pulse oximeter, and I was impressed with its performance and ease of use. Here’s an in-depth look at this essential health monitoring device.**Design and Build Quality:**The pulse oximeter features a compact and lightweight design that makes it easy to carry around. It fits comfortably on the fingertip and has a user-friendly interface with a clear digital display. The build quality feels sturdy, ensuring durability over time while maintaining portability.**Ease of Use:**One of the standout features of this pulse oximeter is its simplicity. The device operates with just one button, making it very accessible for users of all ages. After placing the device on my fingertip, I only had to press the button once to start the measurement. The results appeared on the LCD screen within seconds, providing both my blood oxygen saturation (SpO2) level and pulse rate—making this an efficient tool for monitoring my health.**Display and Readability:**The display is bright and easy to read, even in low-light conditions. The numbers are large and clear, which is especially beneficial for elderly users or those with visual impairments. Additionally, the device provides a color-coded indication of oxygen saturation levels, making it simple to interpret the results at a glance.**Accuracy:**In terms of accuracy, the pulse oximeter did not disappoint. I compared its readings with those from a professional medical device, and the results were consistent, reassuring me of its reliability. This accuracy is crucial, particularly for individuals who rely on it for managing health conditions such as COPD or other respiratory issues.**Battery Life:**The pulse oximeter generally boasts impressive battery life, lasting for several hours of use on a single set of batteries. It also features an automatic shut-off function after a short period of inactivity, which helps preserve battery life and makes it eco-friendly.**Overall Impression:**In conclusion, the pulse oximeter I evaluated is an effective and user-friendly device for anyone looking to monitor their blood oxygen levels and pulse rate. Its ease of use, accurate readings, and portability make it a valuable addition to any home healthcare toolkit. Whether for personal health monitoring or for those with specific medical conditions, I highly recommend this product for its reliability and functionality.

***UPDATED***After posting this review, I was contacted by the company I bought from. They offered to refund or replace, I chose a refund and it was given immediately. My conscience re this review lead me to start asking questions. So, after significant research into the issue, I have determined that my previous star rating was based upon my FEELINGS instead of the facts. I have changed my previous star rating and this review to reflect the facts rather than my feels.TLDR: If you NEED TO KNOW EXACT OXYGEN SATURATION THIS MAY NOT BE THE TOOL FOR YOU. THE READINGS ARE ABSOLUTELY FINE IF YOU DO NOT NEED TO KNOW EXACT NUMBERS FOR MEDICAL REASONS!!!Know that the use of "home" use is to distinguish it from PROFESSIONAL use in a medical setting. Like, if you are a nurse, or a CNA and you need a pulse oxy--this is NOT the one because it is for HOME use.[My feels said: I hope that it is not used to defend inaccurate readings from this meter as a whole. I mean, even if it is for sports & home, it should be close to the real % shouldn't it? More than 1-2 % off the oxygen reading on this item should be considered a problem since it is made exclusively to read the pulse and oxygen. It should NOT be explained away by stating that it is for "sports" and "home" use only.]Reality says that for the stated uses on this product's page, 4% IS a very acceptable margin of error for this product. I'm leaving my opinion here to help others who may have the same views to NOT misjudge this product for a technical issue based upon my formerly uneducated opinions. The fact is that people who are seeking it for sports will KNOW about the margin of error while Home use clearly distinguishes its purpose. My assumptions lead me to draw incorrect conclusions. Humble pie eaten.That being said, I thought this pulse oxy was perfect...It looks very nice, and you can turn the reading to any angle just by pushing the button.I am leaving the previous review (below) here for transparency; it is, for the most part, inaccurate assumptions on my part-some actual research helped me to learn this about myself. The reality is that the proper usage is stated clearly in the product's page. I made many assumptions about my own proficiency in determining the use of the product.Mine is off by at least 4-5%--which, I do not see as an acceptable number no matter WHAT the use is for this product--it is the ONLY JOB IT HAS--IT SHOULD BE ACCURATE. Anyone can GUESS what their pulse and oxygen rates are...I paid for this pulse oxy to be SURE I was correct. Oh, and at the hospital, the pulse readings from this monitor were spot on every time I checked--and I was there on the machine for almost 5 hours.So, if you buy this, I would advise finding a way to check the accuracy--maybe with your doctors office? I had to use the hospital because the doctor using a small device similar to this one and I did not know if that was a good measure of accuracy as the large machines at the hospital.Good luck folks, this is a really nice looking product, with some really nice features at a great price. But MAKE SURE IT IS ACCURATE. And, even if it is not accurate, once you can use an accurate monitor to check yours, just math out the difference and you'll have an accurate reading--I HOPE...I have not been able to check the frequency of the occurrences of the error...but it was consistently incorrect for almost 5 hours so I figure my margin of error is around -4.5% overall. That means that when I read my meter, I need to ADD 4.5% to what it says and it then becomes an accurate reading. Annoying, but it does work and is better than just giving this to the grand kids to play with.
