A good little mutifunction drone!
The Holy Stone HS161 Optical Flow Drone is a mid-sized (254.76mm L x 219.96mm W x 31.75mm H), surprisingly light (124g {4.37 oz.}) drone that features optical flow stabilisation, a rechargeable 1S (one cell) 1,000mAh Li:Po (lithium polymer) flight battery, and the ability to manually tilt the camera's lens over a 60° range.
What makes this drone unique is that you can use it as a flashlight, a still & video camera (without the transmitter) and a USB power bank that can recharge your cellular telephone handset if its battery is petering out!
It flies surprisingly well considering its size and weight.

488nm blue in a directly-injected diode laser! WOW!!!
5 of 5 found this helpful The first thing I did upon receipt of this wonderful little laser is run it through my spectrometer. Judging by the beam color, I figured that it was really close to the 488nm argon-ion laser line; imagine my surprise when it spectroed at 488.3nm! This is right where it ought to be.
The next thing that I did (after analysing it spectrographically) was to remove the battery & collimating lens and have a look "down the barrel" as it were. I saw a laser diode in (what I believe is) a standard 9mm can. Between these, I determined that it was in fact directly-injected and not DPSS like those now-common 532nm green lasers.
Unlike most other laser pointers, laser pens, and portable lasers, this little guy is waterproof (the photograph of it in the toliet tank pretty much says it all) and submersible to 5M (~16.4').
I'm extremely happy with my little cyan-blue laser, and I can't recommend it enough! :-)

Proprietary baterry, poo-poo!!! :-(
1 of 1 found this helpful Very nice drone, but not very nice to have a proprietary battery. Mine would never read more than 84% charge (two different chargers tried) and I'd be damn lucky to get two minutes of flight time before I get the dreadful low battery warning followed shortly by the drone simply falling out of the sky. I DON'T BLAME THE SELLER, I BLAME HUBSAN FOR THIS!!!
