We have number 2, bought it for DS's main xmas present last year. He loves it and it's very cute, looks lovely in the lounge and is played with daily without fail. We left the door off the microwave and put the plastic toys r us one in the space (exact fit!) which lights up, spin rounds, beeps etc. We also got a 'working' kettle and toaster. I nearly bought all wooden ones but he definitely prefers plastic as it's more realistic.
Few things I'm not so keen on though. Firstly I much prefer the hob on the Ikea one as it is halogen style and lights up. This alone is worth buying it for I think. The gas-burner style on the little tykes one wastes a lot of play space and DS has no idea what it is. I'm actually considering taking it off and replacing it with a square of black acrylic to look like our glass hob and give some more room for play. Second thing is the fridge part, he has no idea what the ice dispenser thing is. Thinking that's about to get taken out and replaced with a chalkboard to hide the hole. The oven and dishwasher don't have any shelves so are just open cupboards, and the doors open downwards so are always getting stood on. The washing machine is TINY inside, about the size of a cereal bowl. And the sink doesn't come out so you can't fill it up with water. With hindsight I wish I'd gone for the Ikea one and spent the extra money on a cabinet to go with it (a 30cm-wide kitchen wall cabinet with the nexus birch door and some small legs makes a perfect matching fridge btw!)
