Our kitchen is one of those, we bought the house with it there already rather than fitting it ourselves and I can't wait to get rid of it. Most of my issues may be with bad installation and layout rather than the units themselves. The wooden worktops are tacky all the time, apparently they were sealed with an Ikea product, (and I've heard the same complaint from other people). The tap and hob are fairly mobile on the worksurface – although I don't know if this is because of bad installation or that they are rubbish themselves. Also, I hate the gaps between and under the units, they just gather dirt that is hard to get at to clean and offer no useful storage space. On the plus side the units themselves seem really solid (around 8 years old and all the doors/drawers/handles/shelves still fine) & we've got a 3x drawer like Toys19 above and you can get loads in it. So I'd recommend the units, but not appliances from Ikea, and probably better in a large space because they are fairly bulky units.
