I was delighted that delivery was so fast, arrived two days early which is unheard of. However, installation has proven to be not so pleasant. The window vent assembly is too big for my standard sized window in which we previously have installed LG portables. As with the LGs B&D included two sliders, but both the same size. Fitting the vent assembly to the window partially blocks the vent hose hole. Be advised, if you buy this machine, you may encounter the same issue. Here's hoping the operation of the machine will be as problem free as my LG units.
