I'll caveat this by saying that I'm giving it five stars solely on useability, coolness, and plausibility of the results --- not price or scientific precision. If you need something with industrial/scientific grade accuracy, I can't say how this will do (I'd have to test it against inert-gas bulbs that have precise lines), which I don't have handy. I did test it against various daylight and soft-white spectrum LED bulbs (as well as a "UV" (though really barely-UV purplish) flashlight. In all scenarios, it gave plausible results. The screen is easy to use and displays the full spectrum. One recommendation: read the (tiny font) manual. The play and stop buttons are probably not what you think. To take a reading, you tap the power button on the side, not the play (single or multi) buttons. Those are for more sophisticated uses. It took me a while to figure this out, and I thought the device was defective until I did. Just tap the power button and it will take a reading and display it. Also, don't confuse the middle and right-side marker lines with spectral lines. Personally, I think having those as lines rather than ticks is just bad design. Real spectra have lines, and it's quite confusing. Finally, note that a reading takes several seconds. A progress bar at the bottom tells you when it is done. I can't say how precise this device is, and I can't say whether the price point is high or reasonable --- but I find it a nifty gadget. I always wanted to play with a spectrometer, and this one is incredibly fun and easy to use. Note that it doesn't require any external apps. You don't need a phone or computer. The picture doesn't do it justice and makes it look like a phone attachment. It's not. The device includes both pieces, and I operated it as-is right out of the box.

I'm very happy with the HPCS-330P spectrometer. It's easy to use, seemingly accurate, and the multitest option is a game-changer for real-time monitoring, especially during light source warm-ups. The spectrometer itself is excellent and does exactly what I need. However, the experience with Vodeson was disappointing—the included charger was the wrong voltage, and they never replied to my inquiry about it. Great product, poor customer support.
