Good thing, i use it for the chance of a better espresso and modified my machine. Easy Installation, but beware of electric risks!!! Use a housing!!! Besides that: If using a PT100/PT10.0 with two connections be sure to shorten 8 and 9, otherwise it won't work. For 15 eur you get a pretty nice PID. Again: Get a special case for the device unless you know what you are doing!
FYI: Autotuning with an old Gaggia Espresso Machine does a good job, heating phase first gets over 100degres (celsius), but then quickly falls to the desired temperature and holds it. There is some room for optimization, but a pretty good start.

Manual could be a bit better. Also offering a DC Version with 12Volts would be good for a separate electric circuit which wouldn't be that dangerous.
Arrived quickly in good packaging. Didn't have any drama with the customer service people. The product itself is well manufactured, the machining is tight and the product appears as it does in the photos. Everything else works right out of the box as advertised. General quality is excellent and controller continues to perform and operate as expected.
XMT7100 1.3 inch PID Intelligent Temperature Controller
This Intelligent Temperature Controller has the feature to accept two types of temperature probes, K thermocouples and pt100. It\'s small and has instruction to set up. I use it for coffee machine control and works perfectly.

There aren't cons. Maybe it would be good to have 0,1C resolution also with K thermocouples. Actually, you have 0,1C resolution only if you use RTD pt100 probes.
Easy to install, works great with my main board and all readings are extremely accurate. I ran my own tests as soon as I received this and have experienced no problems so far. Design, specs and overall quality all meet the expected parameters. This is a grade A product. Thank you.
