This was just labeled as "Hot Thai" when I got it from Bunnings in Adelaide.
Originally I thought Thai birds eye, but these seem to taper to more of a point and grow upright whereas I think birds eyes grow pointing down(?). They are fairly small, but I don't think they are as small as prik kee nu. Oh, they are pretty damn hot too. I haven't tried superhots etc so I don't have too much to compare to in that area, but I'd say they're probably up around habanero level, maybe slightly milder. Here's a photo from last year
