The Tabulus arrived faulty. The main issue was the battery was giving little over an hour instead of the 3.5 hours
indicated by the wholesaler. If left off and without charging the battery drained and did not hold the charge.
There was also a fault with the battery charging indicator and the unit could not read my mobile phone chip, just giving an error message.
The UK seller ducked the problem , by first not replying, then after being chased up,claimed they were on holiday, then when nothing further was heard, claimed they were in hospital, followed by a final claim that my return and refund request through Amazon had ruined their business.Avoid this seller if they still exist, and the product unless you are lucky enough to get one in working order.
A few weeks after Amazon refunded this purchase in full. Excellent customer care by Amazon.
