The first Pulse activity tracker was well received due to its ease of use and sleek design, and the Pulse O2 improves on it by adding a new blood oxygen sensor and wrist strap. While it may not seem like much, the new strap makes a difference -- Stuff thinks "it looks more high-flying executive than casual gym slob," and The Gadgeteer says it's "easy to put on and take off unlike Fitbit Force straps which are annoyingly difficult."

However, Withings failed to improve some key features on the O2, namely the sleep and fitness tracking. PC Mag notes "you have to manually enable and disable sleep mode when you go to bed and wake up, and Stuff had problems with its accuracy, finding it "pretty wonky" at measuring distance. PC Mag also says the "the heart rate monitor/oximeter just wasn't reliable."

However, these flaws are not specific to the Pulse O2. When you take into account the low cost of the device they should be expected -- especially when compared to some of the O2's higher end competition. But the Pulse O2 still does plenty right, and CNET says it's "still one of the best pure pedometers out there" even if "it's not a big leap forward over last year."

A new wristband and new firmware improve the Pulse and make it a true fitness band, but it's not a big leap forward over last year.

The Withings Pulse O2 activity tracker packs a lot of features, but isn't the easiest device to use in day-to-day life, especially if you're active.

With pulse monitoring and bags of style, the businesslike Pulse O2 is great value but high maintenance.

The Withings Pulse O2 looks just like its predecessor – it’s a small slab with rounded edges and a clear, blue light up readout that’s easy to see while you’re on the go and in most lighting conditions. It tracks steps and can switch to tracking more intense activity ... automatically.

Now, with a blood oxygen sensor on the back, the Pulse O2 is clearly trying to keep ahead of the competition with finer-grained tracking metrics.

Upon first impression, the rubber wristband options (blue or black) are relatively comfortable, but the band that is supposed to resemble a traditional watch band is hard to the touch, rough on the wrists and, overall, looks cheap. Plus, we struggled to get the tracker out of the first band.

The Pulse O2 can keep tabs on how many steps you've taken, stairs climbed, calories burned, elevation, quality of sleep, and your heart rate. It stores 10 days of data, so you can swipe back to look through them and compare how active you've been.

After having skin irritation issues with Fitbit's Force, I decided to return to Withings (I owned the first generation Pulse). While the biggest update with this version might seem like the blood oxygen monitoring, it's actually the included wristband. Having fallen in love with the Force's form...
