Stay far away from a Sansui LifePad

In December 2015 I bought my daughter a Sansui LifePad from HiFi Corporation in Cape Gate mall. In February 2016 I had to exchange the unit due to faulty software as the unit simply refused to switch on. We were assured that the replacement unit had newer/ updated software and would therefore not give us any problems similar to that of the first unit. It is now May and the replacement unit is again giving problems. This time the Sansui Logo keeps on flashing on and off, but the unit again refuses to switch on. There is clearly something wrong with the software in this product.
