Dokoworld 10000 BTU Portable AC Unit

Let me begin by saying that we have purchased three of these particular portable AC's this Summer ( 2023 ). The Good: 1) reasonable price with Discounts... 2) They do put out a decent amount of cool air. but... The Not-So-Good: 1) The Hot Air Exhaust Hose and especially the "Window Kit" are Cheap, Poorly Designed, and in my opinion, are the Fatal Flaw in this ( and likely other makes ) Portable AC. In order to install the Window Exhaust kit, we had to cut one of the cheap plastic panels in order to fit our standard sized windows. Then, after connecting the Hose assembly to the Window kit, the hose kept falling out of its connector, even using the provided single, very small screw that does not hold the weight of the exhaust hose. This means that at almost any time the AC is running, the Hose Assembly can and often does spontaneously disengage from the Window vent. This results in all the Hot exhaust air being vented into the room while any cold air is exiting the open Window vent. Not good, and for me, a serious design flaw that tends to negate any other positive things I can say about these AC units. And I have read many other Portable AC reviews from customers, it seems this " Window Kit" problem is somewhat common. Why manufacturers can't spend a bit more time and money fixing this design flaw is maybe easily explained. Perhaps, if they can sell us these defective products - that ultimately will fail prematurely - they can just keep expecting we consumers to keep re-purchasing cheap junk over and over... year after year. Sounds like a conspiracy? Well, you only have to research the history of Light bulbs and you may find that many decades ago, those manufacturers built-in "limited Lifespans" in their products, solely to sell more lightbulbs to an unsuspecting and ignorant public. Unfortunately, I guess it all comes down to greed by those who profit on our implied acceptance of inferior products. I hope this review is helpful to those who are contemplating buying one of these AC units.
