Just assembled four of these. They look great, and what they say about them is true ... they're not going to get blown around by the wind (unless its an bad hurricane or tornado). They are heavy! That's both good and bad. If you can put them in one spot and leave them (or just move them a little from time to time), that would be best. If you have to move a bunch of them a distance to mow the lawn, they might be heavier than you want.  But I like them and I think they're going to work out great!
