Yes, I used one for about a year until I found a deal on a gently used Auber PID. It works quite well, but it doesn't have the fine control of the Auber. (you'll still see temperature swings) The 220° max was slightly annoying, but I just allowed for extra cooking time while using it.
I bought the pre-wired one.
The Auber will give you tighter temperature control, and you can program it to perform multiple steps.
