After several searches and hesitations on the model to choose, I opted for the latter. It is very efficient and responds very well to navigation during use. Also nice not needing to turn it off, just fold the flap and when were needed, the flap is lifted and is desuite operational. Started by the tablet is nice ca very good finish. The hitch is too long a load, I do not know if this is from my tablet or model but generally takes 2 hours to reach 80% and then again 2-3 to 100%.
