The AC Infinity Grinder Card is a impressively solid and well-designed tool. It arrives securely packaged in a resealable pouch with a rigid cardboard sleeve, which adds to the premium feel. Constructed from a sturdy grade of aluminum, the card has a satisfying heft and resists flexing, ensuring durability. Grinding is smooth and efficient, though its sharp teeth demand careful handling to avoid nicks. Its standard credit-card size makes it the ultimate in portability, easily fitting in any wallet. For a discreet, heavy-duty, and highly functional grinder, this card delivers excellent performance without any notable drawbacks.

After a disappointing experience with a flimsy portable AC vent kit, this one is a revelation. The quality is immediately apparent; it's constructed from heavy, robust materials designed to last. The kit is incredibly versatile, with adapters to fit a wide range of window sizes and both 4-inch and 6-inch hoses. My specific need was to vent a CNC engraving and laser machine, and this kit has been perfect for exhausting smoke and dust. The ultimate test was installing it in the window of my garage door. Despite the constant movement of the door opening and closing, the kit remains secure and shows no signs of wear. An excellent product that is easy to install and built to perform.

If you're deep in the AC Infinity ecosystem, this Wireless Transmitter and Receiver two-pack is an absolute game-changer. It effortlessly eliminates the cable clutter between your controller and devices like fans or supplemental lights. Setup is a breeze: just plug one end into the controller and the other into your device—they pair instantly. This simple upgrade creates a cleaner, more organized tent, making it easier to manage your environment. A brilliant, no-brainer innovation that delivers fantastic value. Highly recommended!

After careful research, this fan has proven to be an exceptional solution for ventilating my 13x11 workshop (approx. 1200 cubic feet). It efficiently removes epoxy vapors, sawdust, and paint fumes, capable of a complete air exchange in just six minutes at full power.

After extensive research, I selected this model because it uses a metal fan, unlike several competitors that rely on plastic fans. Those models had numerous complaints about premature failure due to friction and noise from balancing issues. This unit, however, runs quietly and provides excellent airflow. A very satisfied purchase.

Very professional and quiet. I just received them and installed them on a digital console in my recording studio. I'm very impressed; they are incredibly silent despite their robust appearance. Highly recommended. I loved them and will buy more to have as backups.

I returned the a4 for s4 & starting my first grow will let you know.

Had a 4 inch Vivosun inline fan that I replaced with this AC infinity 6 inch. Let me tell you this thing is as quiet as a whisper. Even at level 10 it's quieter then the Vivosun at level 4. Definitely would recommend this to anyone growing indoors.

Saved my grows humidity by replacing my unit that was having fan issues, amazing support thank you!!!!

This is a solid, accurate temperature and humidity sensor. Before integrating it into my system, I tested the probe against my existing environment and found it was only off by 1-2 degrees, which is excellent for the price. Its compact design is a major plus. I keep it outside my grow tent to free up interior space, which is a great feature for maximizing every square inch. A heads-up for buyers: this unit does not have built-in Wi-Fi or Bluetooth. To get remote monitoring, you'll need to pair it with the brand's separate management controller. I did exactly that and purchased the AC Infinity Controller 69 Pro. The combination is fantastic. I can now monitor and control my heater and humidifier from my phone, which has completely smoothed out my temperature and humidity curves and eliminated sharp spikes. Achieving perfect VPD is now effortless. I'm replacing a Grovee heater that showed wear in under a year, so this feels like a much more durable and capable solution. Highly recommended, especially if you plan to use it with a smart controller.

Outstanding customer service, timely and professional, that’s why I’ve been a customer since they started selling products for growers!

very good on time

Own lots of your stuff have had no issues with anything will continue to upgrade with this product

I own several pieces and use AC Infinity exclusively. In the past they have helped me sort out equipment issues and since then everything is running perfectly I just received my dehumidifier and it’s amazing. If anything I think improvement can be made in the app. I have a couple suggestions but unsure where to send. Overall very happy.

Absolutely love it all! Top notch equipment from top notch people customer for life!!!

Great service, fast shipping.

I had an issue with 1 fan and they replaced next day. Thank You!!

Had no problems , ordered them and they were delivered promptly.

My native hibiscus seeds, which need a moist environment, sprouted in a remarkable 5 days using this kit. The dome is sturdy, seals perfectly, and is very user-friendly. I was so satisfied with the results that I've already purchased two additional kits. Highly recommended!

Super easy to get my warranty claim handed for a terraform 7. It's like they knew it was a critical situation without me having to ask. That's knowing and helping your customers.
