My first order was received with a wet interior box and almost empty bottles. Since the exterior box was dry, I feel like this came that way from the warehouse and not due to shipping.I used this product once many years ago and was not happy with the results. This time the windows look great! I am good at following directions, so I don't know if maybe the formula had changed or was user error the first time. I used to use a window cleaning service but hadn't the past two years, so they were over due. Glad I took the chance again.Product works well but won't order again. We will purchase in store to avoid losing a quarter of each bottle to leaks. Was also packaged with a clothing item which was wet when receivedThis product is certainly easier than hand washing the windows. It cleaned my outside screens really well, too.Still on my windows, although the glass was clearer, it did leave some streaks and some spots. At least it was apparent the window glass was clearer between the spots and streaks, and had been cleaned.I have well water and the well water is hard, containing calcium and Magnesium, that may be the issue. That could account for the mixed reviews, ranging from spotless to spotted.Nevertheless, it is better than doing the windows by hand. So, I will purchase and use again.I still hire an inside/outside window cleaner twice per year. This, works nicely for in between those times.This is the first window cleaning product that actually left my windows clean and clear with absolutely no scrubbing! Even the lower windows with screens came spotlessly clean. Highly recommend this product. A+ and 5 Stars*****Very easy to hook up. Very easy to operate. Don't use it in direct sunlight! Use in the shade or a cloudy day. Otherwise you may get streaks from the heat on the glass.Reaches up to 18 ft. high! Cleaned all our house windows and still have some left! I highly recommend this product! ?I've used this for years on my outside windows. I like this as it shoots a stream strong enough to reach my second story windows and eaves. I use to this to wash my siding as well and it leaves no streaks on the windows! I've just done my neighbors windows as I had leftover and they were also amazed.Easy to be use and really clean the windows.I’ve used this product for years. On a nice sunny, breezy day! Quick and windows turn out great!This is a rip off..don't buy here
