I have participated in several Massdrops for the very similar Nightcore TUBE keychain lights, I love them and purchased a few dozen, they make great gifts too! Other than the Nightcore TUBE appears to be much brighter according to specs, and the TUBE is translucent, so the entire light glows in a very cool effect; what's the difference between these two lights? I see no advantage to buying these Nextorch over the Nightcore TUBE's. Of all the TUBE lights I've purchased, only one light did not work out of the packaging. I was unable to get it to work, So I'm guessing that's fair to good quality control.
