However, there are some weaknesses that can only be expected in the price range of some kind.
The gravierenste this is the state / the foot. He is extremely shaky and you have when you indelibly really uses it as a touch screen, almost always feel he breaks the same or if he surges backwards when too much "toucht". He used commercially up with us, we have the safe side something fixed him.
About resolution and response rate, I can only say something limited. The resolution has been set for us simple (800x600) - it's just only a keypad.
The reaction and accuracy can however gladly times something to be desired. The first phone we were given, had made the use of the adventure after a few days. It was like time the button is pressed, the half of the screen was loose time away from his fingers. These goals could mur temporarily by (multiple) boot the system off. As it turned out during a conversation with the seller, this error probably like to occur with this model, and the monitor had to be replaced.
Here, the seller was accommodating as much. Since the monitor for our daily business is irreplaceable as such, we have received a replacement unit within 24 hours PRELIMINARY. But of course we were very grateful and I am no longer a long time lived as a businessman today, I want to mention here also necessarily!
But of course this does not change the technology of the device. It's unbefriedigent produce a device that periodically aufweißt error.
The replacement unit for over 6 months now but running properly. However, the accuracy is not always 100%. The Mobile features better. For our purposes, but adequate. Similarly, the sensitivity of the touchscreen.
All in all I recommend the device to all those who need a low-cost solution for simple use and where no Grobmotoriker take over the operation. We will use the machine until it gives up the ghost. But next time I'll spend a few more euros.
Positives:
++ Price
+ Reliability in continuous operation
+ Power consumption
Negatives:
--- Stability
- Precision (the replacement unit)
