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.

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.
