I have one of these and it is the answer to my prayers! My daughter (a very clingy baby) enjoys sitting in it, I usually get a good half hour of peace at least, but now she's taken to falling asleep in it for hours too- even better!! I think its well worth the money, it looks lovely and has lots of different settings, movement, lights, mobile etc to keep baby entertained.
Only drawbacks, a bit of a bugger to build plus it takes up a 1/3 of your front room.
