This laser is hefty and ergonomic, and its teal beam color is absolutely gorgeous. The optics, however, are very poor. Rather than a pinpoint accurate beam, there's a large rectangular shape cast on your target surface along with the bright spot. Very disappointing.

I cannot get the batteries right you recommend the 18650 but this is only 3.7 volt and gives a very poor light I tried using 2 x CR123 Lithium non-rechargeable and these work well at 2 x 3.7 volts (7.4V) is this higher voltage what is needed?

Shipping took forever, but LPS cant really be blamed for that this time of year. Laser is great, LPM read 405mw. Bright beam, small dot. Very happy!
