It is quiet and fast.One issue I have is that when you have the power to go off, you have to manually touch the button to turn it back on. Maybe there’s a setting I don’t know so again if you have it set up to a timer if it turns off you have to go touch a button to turn it on but other than that does what it says it supposed to and it’s good. No five star because kind of a drag you have to manually go to touch the button. ### ⭐ 1.0 out of 5 stars I can't get it out of program mode and get it to run *by J***K on Reviewed in the United States on January 9, 2023* I can't get it out of program mode and for it to run ## Frequently Bought Together - iPower 4 Inch 130 CFM Inline Duct Speed Humidity Temperature Controller, for Hydroponics/Grow Tent Ventilation, 4" Fan, Black - AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust - iPower 4 Inch Air Carbon Filter Indoor Plants Grow Tent Odor Control Scrubber with Australia Activated C for Inline Fan, Prefilter Included, Silver --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/455183638-ipower-4-inch-130-cfm-inline-duct-speed-humidity-temperature](https://www.desertcart.sg/products/455183638-ipower-4-inch-130-cfm-inline-duct-speed-humidity-temperature) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-07*
