I know this is an old thread, but I've been wondering about this myself lately.

I rarely see them mentioned in the modular discussions and channels I've followed so far. They always have modules available that seem pretty affordable for what they do, with an interesting design aesthetic, but they just seem so glossed/passed over for the most part. I briefly had a Mini-Shimmery in my "first wave" of modular purchases as I was getting into it and setting up an initial rack, and while I didn't hang onto it for the long term, it was a cool enough little unit for its price.

If anyone else has good/bad experiences with Blue Lantern or their modules, I'd be curious to hear impressions.
