i wouldnt say it was better than any other on the market,
it dose the same job as the others but at a fraction of the cost, loads of people have problems with the digital ones, you get an airlock and they shut the system down, this carrys on and can pump it out,
my controllers are rated at 15amps and fused down to 10amps, the digital ones are mainly 7.5amps. so theres extra protection there is anything should happen,
plus this has a wireless switch that can turn it on and off,
the cost of this is still less than the the just buying a digital one!
