I like the RRT-01 too. Specifically, the 2014 edition. I find the 2019 and 2020 versions just a bit too heavy. If only they used an aluminum instead of brass pill.
However, the 2014 RRT-01 isn’t perfect:
- The ring takes space. While not large, the RRT-01 certainly isn’t the smallest light around for its battery type.
- I thought the ring was intuitive too. But when I handed my RRT-01 to someone she tried to press on the lanyard ring on the back and wondered why the switch didn’t work.
- While the ring isn’t likely to accidentally turn on in the pocket, I have had it happen. The ring is loose enough and the knurling grippy enough that just shifting around in my pocket did cause an accidental turn-on. This is disturbing since the 2014 RRT-01 has no low-voltage protection. Still… this only happened to me once, so the chances are very low.
- Low output. Even when updated with a 2020 RRT-01 driver, the output on an RRT-01 isn’t going to blow your socks off. I wish they had a driver that provided as much output as the RRT-03, but with the UI of the RRT-01.
Overall, I still rate the 2014 RRT-01’s UI as probably the fastest to use and most intuitive out there.
