Reactionless Thrusters for real???

There isn't widespread reproducibility; there seem to be two groups who have found anomalous readings, neither of which is of any note.

There are a vast number of ideas that are not worth testing. The original theory of the EMDrive was based on the author being incompetent at basic geometry, so even if something is going on, it's not what they think it is.

There are basically a couple possibilities for what's going on:

1. Some sort of measurement error.
2. Some sort of peculiar interaction with the testing apparatus.
3. Violation of basic conservation laws.

Both explanation 1 and explanation 2 mean the device is useless as a space drive. Explanation 3 requires way more evidence than has been presented, and is not worth even considering at the moment.
