Review on 🌡️ AGPtEK F/C PID Temperature Controller with Dual Display and Programmable Digital Control TA4-SSR Solid State Relay - 2 Alarms Included by Fisseha Rodgers

This thing is powerful. Other reviews mention issues with the manual and that's mostly true, but I got it enough to use the product properly. I was able to control my homebrew's fermentation to +/- 0.1F of setpoint. It's definitely going to take a long time to figure out how to hook up this thing and how to program it if you're not techy, but definitely not rocket science. I was able to plug it in and have it up and running within a couple of hours. Runs consistently and is totally worth the investment.
