This fence is good, quite high and the steel is strong.  The lock closes well, but the minus is that nothing holds the door, just a hook from which the door can fly off quite easily when opened.  The steel bars do not go deep into the ground and therefore the fence is not stable enough, especially if the dogs will lean on it.  I have two German Shepherds, so I took 3 sets so far and we ourselves additionally attached them to the ground and also fixed the door.  In general, I am satisfied with this purchase.
