I bought this product, not because I have toddlers, but because I have wall sockets under my computer bench and it stops my feet knocking the wall socket power off switch! Ideal! Also I think it helps unsightly wall sockets look better hidden away. Whats more is that they are very easy to fit and just clip behind existing wall sockets front panel.
Just one disadvantage is that I noticed some small wall sockets that have a small front panel, the socket cover only clips behind the top and not the bottom. Which means the bottom raises slightly when lifting the cover up.
