Shoppers racing to buy device that 'reminds them to exercise'

Fitbit has long been an industry leader, with reviewers often praising its sleep tracking and Daily Readiness Score, which advises whether you should be active or take a rest day, features as top notch. Among the many Fitbit products, the Google Charge 6 is stand-out, and offers 6-month premium membership, seven days battery life and Google Wallet and Google Maps.

And what's more, thanks to a recent free software upgrade, there are some nifty new features. Among these is an update to Auto Detect, when your device detects an activity, meaning it now recognises rowing, elliptical, and spinning. The software update, free to all compatible devices, also promises more accuracy in stats and outdoor mapping thanks to GPS improvements.

The Fitbit Google Charge 6 is water resistant up to 50 metres, and has 40+ exercise modes, and all-day activity tracking, meaning you can get a really good, consistent picture of your activity levels.

Someone else said: "Had a cheap version before but I wish I'd gone for this to start with. Light and comfortable to wear, comes with 2 lengths of strap. I might treat myself to other colours as well." Not all praise has been glowing though.

One buyer said: "The battery life isnt too great but there are quite a few sensors running." That makes sense - if there is a lot happening in the background it may well drain battery. One user took issue with the GPS connectivity on their device saying: "Takes ages to connect then continually drops out." Worth noting that many external factors could affect this too, like if you're running in an area with bad signal, you may not get the best connectivity.
