I bought these and now we take them to the park every time we go, as the children love playing baseball with their own diamond. The beauty of them is that you can set them up anywhere, in a back yard or grass park or on tarmac. The diamond can be as big or as small as you like so can be adjusted to suit the age of the children or adults playing. I am very glad that I bought this set and I am sure that they will last us for the rest of our lives! The set is made of durable rubber so can't blow away but it is a little heavy, at least for me. So I always put the set in the basket of our stroller with our balls and bats to take to the park, that works perfectly.
