Fingertip Pulse Oximeter, Blood Oxygen Saturation Monitor (SpO2) with Pulse Rate Measurements and Pulse Bar Graph, Portable Digital Reading LED Display, Batteries and Carry Case Included

UPDATE: I gave it another week and gave up, BUT I reordered another one and got it yesterday. I was VERY pleasantly surprised that it immediately responded and gave me a reading without a long wait. PLUS, the reading was accurate! So, the replacement I've gotten is as good as my dead one, so it appears that the other one I got was defective. Of course I've only had it a little over a day, but it's giving me accurate readings from both hands. It's not PERFECT, but it's consistently giving me accurate readings ...so far. I have really bad COPD and I take my oximeter readings every day and usually several times a day. I like to check and see how my oxygen levels are before and after activities, plus when the weather gets hot and humid making me have "bad air days," so I like to see both my oxygen level and my heart rate. It helps to guide me in whether I'm needing an oxygen boost or not. I don't know why they manufacture and sell an oximeter if it's not designed for medical purposes? I'm not expecting hospital grade quality, but I do expect accuracy! Anyway, I'm glad that I decided to give this another try. It is a good quality product. I hope this one lasts me for three years like the previous one! The 5 stars are for my older oximeter that lasted @3 years. BUT, the same identical oximeter that I got last week gets 1-2 Stars. My video here is showing what happens to my very frequently used 3yo oximeter when it is ready for retirement. I tried different types of new batteries, but each time it comes on, but doesn't do a reading and just turns itself off. This WAS a very good oximeter. It gave me timely accurate readings! I ordered another identical oximeter from Amazon and got it last week. I read the 1-2 star Amazon reviews prior to ordering and it appears that the 1-2 stars are definitely correct about the decline in this product. The housing is almost identical, but I noticed either a flaw or bad quality control in the battery housing being a bit "off." The batteries took a bit more effort to install, plus the cover didn't want to go back on properly. The center between the two batteries is now grey where my older device it is white. So, due to this neutral grey change between the batteries, it seems to me that there has probably been changes to the electronics inside to properly accommodate the newer housing. As a result, the product is no longer reading in a timely manner nor is it very accurate. I've attempted to use it several times every day and see if it just needs to break in. It was taking more than 30 seconds to finally display the numbers. Next... The numbers are really wonky. My normal oxygen usually reads 96-97. This is giving me readings at 95 and downwards. Yes, I'm very aware that the oxygen readings can be different from your physical activities and the heart rate reading will reflect the change as well. But this just isn't giving me consistent readings and is VERY slow to respond. I'm going to give it another week to try to break it in, but I don't think it's going to make any difference. Perhaps this is one unit that got missed by quality control and just defective, but reading the current reviews, I don't think so. I think that these are being mass produced without any quality controls whatsoever. It's really a shame because it was a very good product. It's even rated as first pick of ten on a Google review website. I'll return to update it after I have assessed it more this next week and if I will have to return it. In the meantime, I wouldn't recommend anyone buying this oximeter. I hope I will be able to exchange for another one to try and hope it's a good working copy. As it currently stands, this isn't worth anything near the $20 USD. It's more expensive than others and better quality housing than many I've seen, but I wouldn't spend $10 USD for the unit with what it is today. I believe in giving a previously good product a fair chance and that's my plan with this product. If the replacement does the same thing or similar, I'll definitely not give them another chance. Oh yes, I have another oximeter that I got through the senior plan and it's a Medline brand. The designed housing is a total nightmare (plus it's ORANGE)... it's upside down on your finger so you have to turn your hand around to read it, plus the oxygen read is on the bottom part of the display. Putting the batteries in and out takes a good set of skills. And it's VERY inaccurate. BUT, it is fast for the display. Avoid the Medline orange oximeter! It's not worth the batteries!

Wonderful and does a great job; just remember to put the batteries in the same direction for this one

Accurate and a great price

I have found this to be a trusty pulse oximeter.

I was very pleased with this Blood/oxygen reader. It seems well built, provides a readout that is easy to see and does in in a matter of seconds. It has just one button to turn it on and then it shuts off automatically this is very convenient. I like the fact that it uses (2) AAA batteries since they are easy to find and for me much better than button batteries. I would definitely buy this item again if I ever needed another.

Awesome product for a great price. Awesome seller with great expectations. Thank you for the great shopping experience.

This is a great item

It works!
