The A/C works great. Really cools the area nicely. I did need to cut the brace that goes in the window and it took a second for me to figure out what the pieces were for. You will still need to have caulk or some way to seal the window piece. Water does come in after rain (I live in South Texas where it barely rains - so not big deal for me). I cut out a cardboard piece to go between the window sill and the window brace. The part that comes with the unit is maybe about 1/4" thick and my window sill is about 1" thick. We also have scorpions, snakes and such - so I'm not taking any chances in my kid's room. The drain cord could be longer, it will not reach the window and the height would cause backwash anyway. We have a little bucket that we have to dump a couple times a day and a little fishing bobber rigged to easily see the height of the water. You may need to dump more depending on your humidity level (it's dry here). The sleep option just dims the light a little, not a major amenity. I do stress that the system does cool quickly. I really cannot gauge the loudness - I feel it's loud, but we like quiet and it's a startle when it kicks on and off (we'll probably get used to it over time).I love this product. Great large vents, shuts off when reaches the desired temp. easy to install, remote control. Visit the ZAFRO Store they were great. Fantastic customer service as well. very pleasant when asking questions about the product, like dimensions, etc. Great AC Unit I love it :) thank-you so much Zafro.This little AC unit is very powerful and cools any small area within a few minutes. I use it in my bedroom which gets quite hot during heat waves and warm California summers! Once installed, make sure you do not need to move it too often as it is fairly heavy, fortunately, the 4 wheel casters make is easier to roll but on carpet, it is a bit more difficult. The only negative was delivery and packaging which were inadequate for the weight of the unit but prompt response from excellent customer service took care in resolving this issue.I had a issue with the product but the company and customer service agent Shey are top notch and communicated with me efficiently and offered a full refund after the return period. I am grateful for the attention to service.I have a small studio apartment and it works for the space. Make sure to keep a large container under the hose for the humidity draining!Used in garage!Noisier than I’m used to.
