Would definitely go with the 300 lumen version next time
I've really likes NiteRider lights in the past - my first 300 lumen front light lasted 4 years, was really easy to take on and off with a robust rubber strap, it had good battery life and was sturdy and reliable. I eventually decided to replace it as the battery life was waning, and the micro-USB port worn out resulting in unreliable charging, and this time I went for the brighter version of 500 lumens. Annoyingly, the battery life is only around half of what it promises on the packaging, and you sometimes only get 20 minutes warning that the battery is low and therefore you don't necessarily get home in time before it dies. I would give NiteRider the benefit of the doubt and buy a 350 lumen one next time, but they need to up their game and ensure they meet their battery life promises! Also, switching to the more robust UCB-C charge port would be good.
