Q & As

Rated 3.5 out of 5 by 26 reviewers.
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
Rated 5 out of 5 by Worth every penny Aesthetically beautiful, sleek and above all accurate. I had some reservations due to some of the negative reviews, but I was able to set it up in less than 10 minutes. It syncs to my wifi network and fitbit app on my mobile without any issues. A fantastic product!! 26 May 2015
Rated 5 out of 5 by Absolutely great product These are great. They were easy to set up for multiple users. The interfaces with other devices works well and was straight forward to set up. They seem to be accurate and compare well with other scales, they are very repeatable. The scales are comfortable to use and smart in appearance. I am extremely happy with the product overall. 28 April 2015
Rated 5 out of 5 by So easy to set up. I see that others have had problems, but for me this couldn't have been easier to get up and running. Downloaded the software from and it was an automated procedure. I'm very happy with it. 22 April 2015
Rated 4 out of 5 by Great if you're a Fitbit-er I'm not going to lie, setting this product up was an absolute pain. I got to the point where I thought I would have to return it for not working. After much research on the internet I finally got the scales to sync with my wifi using the 'mobile' method. Once this was set up though it worked brilliantly. I use a Fitbit Charge HR and my wife uses a Flex and we share the scales. It automatically recognises each of us and syncs the data into our own apps separately. It's very slick If you've got money to burn and you'd rather have this data automatically sync into your app then I'd highly recommend it or else just use a pen and paper! 17 March 2015
