I just ordered a Radar. I don't know how the convolution and latency in it compares to things like the Logidy EPSi or Hotone Omni IR. I'll be curious to try it. There weren't any major red flags in reviews I saw, other than some people had trouble updating the software.

There are a couple other mooer pedals that load IR's (GE series, but not all of them).

I don't know how much difference it makes whether an IR loader has the capability to use longer IR samples-- the Radar is limited to 1024 samples-- which I believe is around 20ms.
