The programming interface is intuitive, and I found it straightforward to set up and customize the temperature settings according to the specific requirements of my reptile species.

  • Good to heave
Size: ITC-308
The Inkbird ITC-308 Digital Temperature Controller has been an incredible addition to my home brewing setup. It’s user-friendly and incredibly versatile, allowing precise control over both heating and cooling elements. Setting it up was a breeze, and the dual relay system ensures that my fermentation environment stays within the perfect temperature range. The digital display is clear and easy to read, making adjustments simple and quick. This controller has significantly improved the quality of my brews by maintaining a stable temperature. On the downside, the sensor wire is a bit short for my needs, requiring me to use an extension to reach my fermentation chamber. Additionally, the instructions could be a bit clearer for those who are not as tech-savvy. Despite these minor issues, the Inkbird ITC-308 is a highly reliable and effective temperature controller that I highly recommend for any home brewer looking to take their craft to the next level. Pros: - User-friendly and versatile - Precise control over heating and cooling elements - Easy setup with a dual relay system - Clear digital display for simple adjustments Cons: - Sensor wire is a bit short - Instructions could be clearer for non-tech-savvy users ... show more

  • Needs better instructions
Size: ITC-308
Ok. So, it does a good job at keeping it around 115 F, which is where you need it for making an herbal oil. It's supposed to keep it within the temperature range that you want, but in order to actually keep it at the temperature you want, you have to set it at 1 degree F higher. It's also supposed you to set it to go a certain amount of degrees above your set temperature, and a certain amount of degrees lower, at your decision. I found that it wouldn't go up to the degree above the temperature that I wanted, but it would let it dip to the lower temperature. That's why I said it's actually best to set it to 1 degree higher, so it will stay at the temperature you want. And so it doesn't allow it to slip to too low a temperature, set it to 1 degree lower in the temperature range as well. But, yes, it works beautifully once you do that. The issues: the instructions were terrible. I mean soooo terrible. I got so frustrated because it was so terrible. I had a hard time figuring it out. The manual was not detailed enough. Not to mention it keeps mentioning letters that weren't on the thermostat, and it had letters showing on the thermostat that weren't in the manual. The instructions were very hard to understand, and I had trouble just figuring out how to get it to the Fahrenheit setting, let alone figuring out how to use it. They definitely need better directions, that were a lot more detailed. The good news is if you can figure out out to use it, it's easier to use, and it works fairly decently. ... show more

  • Used to make a DIY meat cooler
Size: ITC-308
I have used 2 of these and a window AC to make a walk-in cooler for hanging meat such as a hog, beef, lamb, or deer. I can set the temp to 36/37 - the ideal temp and they work great to control the AC. I have checked temps with both a Govee and a laser thermometer and the reported temps are the temps I set with the InkBirds. A great solution for a low cost cooler. Also can heat the room in colder months. ... show more
