SPO Medical 903036 Check Mate Pulse Oximeter Review

I am a physician. I use the portable handy small tools to help me get an idea understanding that this one was not approved for medical use.
I am comparing this one to Nonnin's portable pulse oximeter which I had for 2 years and this one does not even come close in its accuracy. In many instances, it was off by 10 points! I confirmed this with actual measurement of arterial blood gases.
I was tempted with the price and the battery life but what's the use if you can't trust the reading?
My advice to you. if you want portable pulse oximeter that you can trust get Nonnin.

Mio Sport Select Heart Rate Watch Review

I read many reviews on this watch, and the one thing that I saw over and over was the complaint that the HR wouldn't display during an activity, such as running. The runner had to stop to get a reading. I took a chance since I would either be walking or on an exercise bike, but lo! I'm even having the problem while walking and while simply sitting on my exercise bike with my legs pushing the pedals. I rarely get a reading while still exercising at a very moderate rate. It seems the watch only cooperates when I'm still.

Despite this problem, I like the watch. All the features work well, aren't too hard to program, and work well for me. The watch is bulky and quite large on a smaller wrist, but there is a lady's version available. I made sure to buy the Mio that offers the interchangeable strap, which is a good thing. One other reviewer complained about the strap breaking on another Mio with no way to replace it. I can see how that would happen over time. The plastic used on the band is rigid and with the bending of putting the watch on every day, it appears it won't take long for the plastic to break.

Overall, I find it to be an acceptable HR monitor with limitations that some, however,might find unacceptable.

About Mio
The story of Mio began in 1999 when it was created by entrepreneur and mother of three, Liz Dickinson. Like many of us, Liz balances family and career, leaving little time for fitness. After several unsuccessful attempts to achieve her fitness goals and shed the pregnancy weight-gain of her third child, Liz turned to a personal trainer for advice. While working with a trainer, Liz realized the key to getting in shape and staying in shape is to practice smart eating habits, monitoring calorie intake, and using a heart rate monitor to ensure that she exercises at the right level. Liz realized there wasn't a product available on the market that would easily help her follow her trainer's advice.
Liz didn't have time to read labels and carry a calorie journal in her purse, nor did she have much patience for the uncomfortable chest strap she had to wear to get her heart rate. She knew there had to be a better way, so Liz used her technology and marketing savvy to create Mio, the world's first heart rate monitor to work without a chest strap. And, it didn't stop with just heart rate, as Mio also has a patented calorie management system that offers a straightforward approach to managing your diet. With the help of Mio and a balanced diet, Liz was able to shed those unwanted pounds and gain the benefits that come with improved fitness: more energy, more vitality, and less stress, and help many others do the same with the creation of Mio's products.
