Really happy with this. Have a giant back yard tent and it gets HOT in there. Bay Area California has low humidity so it works perfect here. 95 degrees out and I can keep the 120sq ft tent at ~76 easily (output at unit is 67-68 degrees). 90 or below and the tent stays 72-73 degrees. Build quality of this evap cooler is really nice. Well thought out design. Controls work great, the swing function is nice to cover a large area with cold air. I also appreciate how quiet the unit is even at high speed. The automatic fill with garden hose is great to keep it going all day, week, month long.From opening the unit up, it is nice to see that it should be servicable in future in case you need to replace the evap pads, pump, etc. I also want to point out I had a little issue when mine arrived and support immediately helped me out and got me the part needed to fix. Great to know they have good customer service!Couple tips for those new to evap coolers:If you live in high humidity, this may not work well for you. But if low humidy, you'll be loving the cool refreshing air.I tend to find that evap coolers work better right in front of a window sucking in hot dry air. Make sure you have something open on the other side to allow ventilation.Ice isn't needed. I never notice any difference with ice. Once it runs for a while, the water becomes super cold anyways. You may need to run for ~30 min for it to get maximum cooling.I also recommend using a calcium filter on a hose to prevent build up.You will be very happy with this unit.
