So far, only 2 stars

When the meter was available at last and was also delivered, I've tried it and it worked equally well at first properly.

Well, it weighs a little more than a simple sleeve in which the instruments actually is on the table, but that's due to design Yes logical.

The application comes with a little practice quickly and easily.

Less nice is that after a few days several times the measurement was aborted in the middle. Partly was the Bluetooth connection off (could possibly be also on iPhone) but mostly the reason was incomprehensible.

You could then also not start and a closing and re-opening the app did not help, because the aborted measurement was still standing in the display.

It also happened that you could not turn on the measuring instruments, here helped only a short remove the battery.

I trade it therefore now first order and hope in the new device, the problems are settled. If so, then that is in any case at least a 4 star - device.

The new device "bitchy" in connection to the iPhone 4S sometimes just rum and that's not at all according mM. I can in such cases, although resort to the measurement by iPad, but that it can not be yes.

Possibly Is it the iPhone, but I do not think so. Rather I believe in temporary problems with the app, which indeed the whole controls.

I have now written to support and we'll see what comes from there. Therefore, it remains at baw 2 stars.

After more than a week has become the "Support" does not answer my question or stirred. Sorry, something can only be answered with star deduction. A device with flaws where the support does not respond to customer inquiries, can not really be recommended.
