Well my Ranco temp controller went out (my fault), so I decided to go with a cheap Chinese knockoff. I do like it has a couple of more features than the Ranco and you don’t have to wire it. Will see how long this one will last. It was rated pretty well. I use it to control the temperature of my beer fridge.
I’ve used the Inkbird for about 7-8 years and it works great. My Inkbird accuracy is +/- 1°F; I wish it was a little closer, but it’s still a nice controller.
I used these as a replacement for Ranco and another brand, expecting them to crap out (I have two extra in the box) - and they work great and outlasted other brands, despite being less expensive! My back up set have not been needed. Pleasantly outlasting my expectations.
I bought a Ranco 2 stage already wired from MoreBeer ~15 years ago, IIRC, for my fermentation fridge and it’s still going strong. They’re pretty bullet proof IMO. After the 3rd Johnson Controls analog controller , I use for my Keezer failed in the same time frame, I went with the Inkbird ITC-308 and am very happy with it. Even if it should fail, it cost about 1/3 what a single stage analog controller would cost today.
I also recently got an InkBird INT-11P-B wireless meat probe and am quite impressed. This outfit makes some great products!
I have had an Inkbird controller for several years. It was an indulgent upgrade since I had a working Johnson controller I just found clunky to use, but zero regrets - it’s so easy, and from my various cross-checks it seems to be accurate.
