This is a really impressive looking and great fun addition to any Brio set. My son got it for his second Birthday and he really enjoys using it - especially watching the trains whoosh down the other side. We don't use the battery-powered engines because they drive him mad (he likes to be in control and push things), so I can't comment on how well these go up the slope. I think the price is pretty good when you compare them with other Brio items and the quality, as always, is superb. I've seen other makes at playgroups and have been less than impressed with their quality, durability and ease of use. I would highly recommend this product for any child who loves wooden trains.
