Only downside is that you end up with a large opening under the air conditioner. I had to fill it in by stuffing a fair amount of foam all along the window sill. Other than that, I would highly recommend this product. It really makes for a very solid and stable base for your unit, especially if it's a very large, heavy unit like mine. Mine weighs almost 75lbs and I don't think I could get it in the window without one of these supports, not to mention the strain on the window its-self with all that weight pulling out on the window if you had no support under it.
