Nonin Go2 Achieve Personal Fingertip Pulse Oximeter

I did a lot of research between brands before ordering this item. Ultimately the deciding factor for me was the company's website. I found that there is a medical grade of this item requiring a prescription and it is the same item. The specifications for the two are listed side-by-side and even the price is the same; the only difference is this one does not require a prescription. The medical grade meters must meet FDA tests so this one obviously does, as well.

I like the continuous readout. From the pictures I was not quite certain what to expect in the readouts or performance I didn't feel the descriptive information was precise on this. The readouts are for pulse rate, blood oxygen level, and a scale that, literally, shows your pulse and the strength of your pulse. This enables you to know if you are getting a strong enough pulse to get a good reading.

After first putting the unit on, I did some moving around, sitting still, and various things to change my activity level. The pulse rates changed accordingly and there were some variances in the oxygen level, as would be expected. Though I have just quite smoking (mostly) I did light up and had a few quick drags to see what effect this would have (lower oxygen at first, then catching back up almost to not-smoking level).

I'm impressed with the unit. It will operate economically on AAA batteries. If I end up using it a lot, I'll probably go to rechargeables for it.

While this one was a few dollars more than some of the alternatives, I felt it would be the most reliable from the research I did. After receiving it, I am extremely pleased with the way it works. I would highly recommend it.

I bought the Nonin GO2 for my mom who uses oxygen at night and has had blood oxygen saturation problems lately. Her level is normally 97-98 but sometimes drops to 90. I wanted her to know when it got low. I researched several brands of home meters. Nonin, I learned, makes professional models costing hundreds. But the GO2 uses the same technology in the home use meter. The difference is that the GO2 is not "certified" thought technically its just as accurate and reliable as a professional unit. The meter is very easy to use. It automatically turns on when placed on the finger. It takes 5-10 seconds to give O2 level and pulse rate. Then it shuts off automatically once removed. A single AAA battery lasts about 4000 readings. It has a great warranty (2 years) and seems very accurate. Highly recommended product!

This is a wonderful and accurate device for monitoring oxygen levels, pulse and strength of heartbeat. I measured it against a professional hospital quality oximeter and it compared accurately well. It just takes a few seconds longer to produce the result. The readout lights up automatically when your finger is inserted and is very easy to read, even in complete darkness. You can keep it on to watch the levels change while resting or while exercising. It doesn't appear to be waterproof, so DO NOT take it while swimming or showering.

I'm grateful to Nonin for making this available and affordable. The fact that it is made in the USA clinched my decision to buy this one. I purchased a case for it to take with me when traveling.

Thanks also to Amazon for availability and reviews in making purchase decisions.

I am a respiratory therapist and I have been using this device for about five months now. It is relatively cheap compared to the Nonin Onyx but as a medical professional I would recommend spending the extra money and having a nicer device. This pulse ox does not read sometimes. (not because of fingernail polish or hypotension/hypothermia; although that messes with the reading too like all pulse oximeters) This pulse ox tends to read lower than usual than most other devices. Why? I don't know.

Is it bad? Not entirely, This is probably the ideal device for athletes who want to check their pulse and oxygen saturation.

In other words, it's perfect for those who are completely healthy and normal, It's only $99 and will work great for you.

Is it great? No, I would recommend using a Nonin Onyx if you are buying to use in a hospital or medical setting,

Cough up 200 dollars.

We bought this when my wife was leaving the hospital with a pleurex catheter and the doctors were concerned about her oxygen usage.

The nurses in the hospital used a Nonin similar to this, just a bit faster (and 3x the cost). My insurance company approved a rental pulse oximeter that cost about $500/MONTH to rent. (This is one reason insurance is so high). My cost for one month of the rental was almost the cost of purchasing this one. No brainer. This works perfectly, is more than fast enough (just a few seconds), and was able to help tell us when we could call the doctor to consider removing the catheter a very important concern for my wife.

The kicker is that I still have this to keep track of any possible additional issues, and the kids like checking to see who can hit the highest number.

If you need a pulse oximeter, I strongly recommend the Nonin.
