Key ring removed from swivel link and small carabiner added for more conveniance. Unlike others I don't find the torch heavy for its size.
Not noticed any PWM in high either.
First battery dimmed in high mode at 3.7 volts (20 mins), so fair warning of low voltage on unprotected cells. Second battery gave me almost a full 1/2 hour on high before any dimming though torch did get a little too hot for comfort and voltage in this cell (different make) dropped to 3.5 volts
Quality finish and very smooth threads (Mine arrived with hints of a covering of machine oil )
This torch will remain clipped to my belt loop for a convenient every day carry
Over all, a great buy and recommended,
Thanks FastTech
