Okay, so I feel the need to "share" my experience just to see if anyone else can match this. The Professional 110 range cooker was supplied with a manufacturing defect and it took 4 months and 7 callouts – with a rmarkable number of nagging phone calls from me to get the second freelance technician I was referred to by Rangemaster to show up at all – to get it partially righted. The wrong feeder "nipple" had been fitted to LH oven so the safety cutout kept closing it down, was the explanation I got from the freelancer, who asked to borrow a darning needle so he could enlarge the hole and make it fire. As he pointed out, it was still VERY slow to light. He promised to come back with the correct part and never showed up.
So finally I rang Rangemaster – just before the guarantee was due to expire – and suggested they should correct the situation. Rangemaster agreed and sent an Aga repair man who turned up unannounced, while I was out. The builder let him in and told me he was ever so nice, gave him some spare parts for his Aga at home. Unfortunately, the Aga man also had not a clue how to repair gas ovens and left in a hurry claiming we had been sent "the wrong part". He took the part that had been supplied with him. So the next technician, from a local service company, said actually, the problem was not the part supplied but the fact that SOMEONE had cut through the feeder pipe. He disconnected the oven and removed the knob, explaining it was now unsafe.
Three months later, I still have a non-functioning LH oven with an empty hole with the knob should be, because incorrect parts have now been sent FOUR times. The pipe for the RH oven, duplicates of previous parts, you name it.
The biggest irritation is that our daughter's birthday party has been and gone, with me shovelling pizzas into our one functional oven at double quick speed. Yes, it is lucky we bought a model with 2 ovens. BUT.
And by the way, the so-called "professional" knobs are a cheap coated plastic. Within a year, the chrome coating was bubbling on most of them and had flaked off sufficiently to justify replacing over half the knobs at just under 2 years.
I chose this model because I wanted gas oven/s, which function better for gluten-free baking and are great for roasts. The only reason we didn't get a cheaper one from Stoves was because the grill fan on our previous Stoves cooker was rather noisy, with a delayed cut-out that meant we were always eating dinner to the drone of the fan. I had looked at the more expensive French range cookers, but their gas ovens were disappointingly set only on totally hot bread-oven type settings, not to cook at slower temperatures. (Useless for doing oven-dried cherry tomatoes or roasted almonds, for example). Do I regret my choice? Yes.
