Sorry to have to say that I am very disappointed with this product.
1. Stability may have been improved, but I feel that this product is not stable enough. 2. Set up is difficult, complicated and took several goes. The support pages are lacking customer connection. 3. Wifi connectivity is limited and unreliable in the home. 4. Data provided is inconsistent - For example Body Fat is 4% out compared to two previous and other scales I have used. Muscle Mass is about 35% off target and puts mine at 14% which is clearly not correct. 5. There is no customer support telephone number in the uk. Emails are not responded to in a timely fashion. 6. The scales are heavy.
In short, data is not reliable and I do not recommend anyone should buy this product.
