Have to say I think this is brilliant. I had read all the reviews before I bought it, so when it came I was a little dubious. It is, what I would imagine to be, the size of a large trantula. It does move slowly although this seems to give it a realistic effect. When testing it out, before giving it as a present, I have to say I was getting a little bit spooked, and I am not bothered about spiders at all. The light up 'red' eyes are clearly unrealistic, but children love this, so who cares. Also it doesn't work on carpet, so if you don't have hard floors I would go for something else. All in all this is a great gift for any child who loves getting one over on an adult!!
