Convenient sized rechargeable torch. Good brightness for its size.

Compact, feather-light, and with impressively-long runtimes from such a small battery.

The battery-level indicator is really useful.

The beam is very wide-angle and illuminates a whole area rather than a spot.

The low level (1 lumen) is quite sufficient to navigate a dark room, and it's what I use the most.

There is not a huge *visible* difference between the mid (20 lumens) and high (45 lumens) levels. It might be better to have just two levels, for simplicity, or reduce the mid level to 10 lumens, for much longer runtime.

Maybe provide a small hand-strap instead of, or in addition to, the keyring.

Overall, a very nice little light! Highly recommended!
