In a general sense, the reliability of things like aftermarket ECMs is based on many factors, with most of them centering on user decisions. The better your decisions on everything from wiring and placement to soldering skills and the condition of your charging system will affect reliability.
From the position of failure rate due to design and components; keep in-mind that these are not constructed from automotive-grade parts. That said, most designs are well-proven and failures from components appear here rarely, and we are back to issues created or increased by the user (including component parts choices) as the primary influence on failures. This would indicate for one example, to stay away from inexpensive imported components of questionable source or quality.
If you have concern, these things are cheap, so throw an extra in your boot if that makes you feel better and sell it when you gain confidence in your skills. Otherwise and IMO, make good setup and application decisions and it should serve you well.
