"This is an excellent museum that covers how the things we use were designed, and the evolution in the design of items from early versions to the present day. It was great to see some of the old tech from our past! The building itself is a work of art once you are inside. It took us around 1.5-2 hours to make our way around. It's mostly on one floor and not that large but there is a lot to see. The exhibits have a fair amount of text associated with them. So I would not say this is the best place for very young children. There are other exhibits on which may have a cost. When we went, there was a free exhibit on the technology that could help us as we get older which was thought provoking. There are lockers, water fountains, toilets, coffee shop, and the most expensive gift shop I have seen for some time. Very different things in it from the norm, but even still it felt expensive. I recommend a visit to the next door holland park which was very enjoyable. The museum is definitely worth a visit."
