Product has a design flaw..on sending seller videos was advised to buy a metal BIT for drill or sheet metal cutters to allow accsess to power cable....apparently they have advised other customers the same..so selling it with a flaw..diffrent sites they advertise on contradict each other..ie energy rating and power...needless to say the reality is its the lower power and the higher electric consumption..so if your happy to buy extra tools and do the job yourself Go ahead. ps open it as soon as recieved as they wont entertain a complaint after 24 hours..and you pay return on defective merchandise BEWARE
