Stay away from this device !!!

I rate highly dependent on a purchase of this device !!!!!!!!!!!!!!!
We have it ordered from Amazon and after about four weeks
no longer worked, the outer display.
After contacting the company Dostmann I have the device
sent at his own expense.
With the new device, the display is partially unreadable and the outer display
got in a few days is no longer connected.
Again I contacted, this time at the expense of the company
Dostmann returned and now it comes with the Noted 'acceptance
denied 'back and the whole cost me 15 e.
The device is worthless and the company Dostmann is not very helpful !!!!
So, stay away from this unit !!!!!
