James,
I'll go along that it is fine to spread some weed killer and tree killer in the clearing around the house. // see my last posting //

But the other measures must always be addressed too. I have seen just too many products out there where it seems acceptable to have eratic behavior of the product and having it reset it self unexpectedly. <big>I for one cannot accept crapping engineering in this way and will always be a voice to make products as robust as possible.</big> I know from years of making products that it is possible and attainable!!
