Q & As

Rated 3.5 out of 5 by 30 reviewers.
Rated 4 out of 5 by More than just a set of scales! At first this seems a bit pricey for a set of digital bathroom scales. There is much more to it then that though. I have found the way the fitbit app and website maps your weight really handy for working out how your exercise and diet regime is going over time. The bodyfat measurer is even better in this regard, as gaining weight may actually mean your are gaining muscle mass and not fat. These scales will work that out for you! If you have a fitbit tracker I would say this is an excellent addition. Adds a lot more to the statistics you gather. If you are a none fitbitter, it's less essential as you really need a tracker as well to get a good holistic view of how your healthy regime is going! 17 November 2015
Rated 5 out of 5 by Fantastic product Easy to set-up and use. Simply stand on the scales and your weight is transmitted via WiFi to your broadband router and appears in your FitBit account and on your iPad/iPhone/etc. Great for tracking your weight, body fat, BMI and complements my FitBit Surge cal burn and my cal intake. 10 November 2015
Rated 1 out of 5 by Absolute garbage This is the worst product I have ever purchased from John Lewis. It will be returned. Setup is a joke. I followed process to register a new fitbit account only to be told that my login details were incorrect. How can they be incorrect for a new account! Overpriced rubbish. The help section on fitbit website is awful as well. 23 October 2015
Rated 4 out of 5 by Looks great and works well Piece of cake to set up with phones and wi-fi but has been confused about who's who a few times since. Easy to sort out, just a bit irritating. The scale looks great and is even telling us that we're losing weight! 22 September 2015
Rated 5 out of 5 by Amazing piece of kit. This bathroom scale has changed my lifestyle. Integrated with my Fit-bit HR monitor, my Iphone and my laptop with ease. It has allowed me to control my weight with little effort. I have managed to lose 9Kg since I bought it, and lost 0.9Kg in the last week alone. It should be remembered that the scale alone is just an expensive weighing machine, its the whole Fitbit package that allows you to take charge of your life. 11 August 2015
Rated 2 out of 5 by What a pain to set up. This is a nice product but I would not have bought it if I had realised it was such a pain to set it up. Poor instructions didn't help either. Would not recommend to anyone. 11 August 2015
Rated 4 out of 5 by Don't be put off several reviews give the impression that this product will be difficult to setup. in my experience it could not have been simpler. just follow the instructions from the online setup page it I was working within five minutes. Every time I weigh myself it automatically sinks with my computer and keeps track of any losses or gains. perhaps a little expensive but in my opinion worth it. 14 July 2015
Rated 5 out of 5 by Oh on!!! Hate them, they tell me how fat I am and sends it to fitbit. Joking apart they are great. They sync automatically via wifi and are easy to use. They can tell whether it is me or hubby using them. The daily graph read outs helps know whether to: 'watch it today you were bad yesterday' or 'yes' it's dropping. The graphs also show BMI and Body Fat. Along with what range they are in. Other reviews had said they were hard to set up so I watched a video on YouTube first. Once set up I had a play in fitbit to figure out how it worked. All quite simple really. Set your goal and go for it. 02 June 2015
