I love my MT2C Pro, the 18650 version. It offers so much brightness and throw in a sleek shape that most pocket throwers can’t match. I’ve got a couple gripes (UI and lack of battery indicator) but it’s the best pocket thrower I’ve tried yet.
MT1C Pro is almost identical to MT2C Pro with a few key differences. It’s ~30% shorter with ~40% less brightness and throw, and ~55% less battery capacity. For those reasons, I recommend the slightly larger MT2C Pro instead. If you’re heavily invested in 18350 batteries, then MT1C Pro may be a better choice.
