First of all, it's not the one I ordered that was delivered; no problem, it was a higher model; no worries so far!
it was afterwards that things started to go wrong: the first time I used it, I put it in the oven and after a while I saw steam escaping from both sides of the appliance, which was abnormal. so I decided to call for help, sent it back and barely a week later the appliance was returned to me, supposedly in perfect working order. OK, so I put it back in the oven and once again steam escapes from the appliance in the same places as the first time... so I don't mind that it's reconditioned, but don't push it; if it had been checked properly they would have seen the fault. In short, I wouldn't order anything from SK HOLDING now.
