In theory it is a nice device. Please pay attention to the fact that, despite of being stated on advertising that the output Voltage could be vary from 0 Volts to 35 Volts, this is not true. The minimum output voltage (even adjusting the minimum input voltage as 7 Volts) is 1.2 Volts, what is so frustrating. So, if you need a lower output voltage, this item is certainly not the better one. This information should be clearly corrected on the advertising of item.
