I like the unit as it is small and easy to carry around - but with that comes the downside that not all "functionsprograms" actually work - at least when following the instruction booklet. Other downside is that it turns off after only 10min - I prefer a little longer.Overall - I would NOT buy it again - I bought already 2 units - but as they were that cheap not going to return them as that would cost more in effort than what I paid.
