We use it.
We have used to cool the H290. It does the job on 90 degrees days. It does have some high fan noise because the unit(fan) run all the time, but you can still talk over it. We have also used it at night to sleep. We use it on very hot days. You have to keep the cheescloth clean that covers the water pump (this helps the vaccum to the condenser). I had a plastic window made with a cut-out in fit on of the side ports for the power cable and the water lines. All and all not bad. It is a heavy unit to lift, but with suitcase type handle's not to bad. It is a well built unit and the service/support is good.p.s. I am a mechanical engineer.
