I received a lengthy call about the prep work I needed to do before the in stallers arrived. I removed the old hood and explained on the call the new one will fit, so the guys can put it straight in. Not once was it highlighted to me the hood would not be installed. I assumed it was part of the cooker/hood install. After I employed an electrician to install it correctly, I then found out the 4 slot in air covers barely fit. if I were to touch the outside of the unit, they would fall out. Rubbish flimsy quality.
