Consumes 4 new batteries in 4 days

I had the WS30 which I was totally satisfied, but then big big concern.
My WS50 consumes me a set of 4 batteries in 4 days, with a weigh of 2 persons per day ...
At first I thought I had a problem loading my rechargeable batteries, with which I have done 3 cycles.
Then I bought new batteries, ditto, I thought, yet benefit of the doubt, the package may have been a concern, but then the second new game consumed in 4 days.

I'll check with the service but in the meantime I do not recommend this Withings scale, but then not at all.
In addition it is no longer impedance meter that proposed the WS30!

150 is abused!

> September 4: in 2 weeks and 3 Sav raises no reply and still the same problem

> 9 September: new message to the service.
Not only does it still consume the batteries in 3 days but we now cover when I replace, impossible to reconfigure the balance to pair the phone, the balance hangs on step 3 of the configuration.
Still no response from the service !!!
How to contact the service other than by email, mystery !!!

> 26 September: two reminders by email: no answers. there is no service on this product! FLEE really!
No way to join the service, it is a shame for a product 150

> Early October: Finally a touch of wonder that service details

> Mid October: RMA and service address communicated to exchange; FINALLY !!!
I now expect the replacement balance hoping she does not have the same problem.

DO NOT BUY!
