NEXTSTAR Ultraviolet Light sanitizer, Ultraviolet Disinfection Lamp, Portable UV Light Sanitizer Travel Wand with USB Charging for Hotel Household Bathroom, Smartphone, Wardrobe, Toilet, Kids Toys

I really like this product. I carry it with me for on-the-go sanitation. I’ve used it in my car, at work, on retail purchases before carrying in and using, and in high-traffic public areas such as the doors and light switches at work.

Works great, easy to hold and put in my purse. I use it on all my deliveries and when I go to the DR.

make sanitizing easier

Far as I know this is working to sterilize my equipment I am a nurse and in home health

small, portable quickly scans all groceries, face masks, dining tables, menus, newspapers plus all mail items received.!

very handy in office

Upon receiving this product, the first thing I did was to scientifically measure whether the light emitted by this device is: (1) UVC, i.e., ultraviolet light, and (2) is strong enough to have any type of material impact on killing bacteria and virus.First, read about UVC, and their cousins, UVA and UVB.In order to have any type of sterilization effect against bacteria and viruses, you need a UVC light emitter, in the ideal range of 258 nm.Anything under 280 nm will have a desired effect, but the lower the wavelength, the better for killing bacteria and viruses.Notice that anything above 280 is NOT considered UVC. In particular,UVB range is 280-315 nmUVA range is 315-400 nmI have a Solarmeter 8.0 UVC dosimeter, calibrated to measure wavelengths of 250-265 nanometers, and I have used it to scientifically measure he UVC light emitted by all of the sanitizers I have purchased.NEXTSTAR Ultraviolet Light sanitizer wand has 12 lights, positioned in a 2 x 6 formation. I can see two different types of bulbs in there: 4 yellowish bulbs, and 8 white-ish bulbs.The configuration is as followsW WY YW WW WY YW WNext, I turned on the device and place the emitted light on top of the sensor of my UVC sensor.Meter shows it's reading in microWatt / cm^2.To give you an idea of how much dosage you need to kill, for example, the coronavirus, search for some NIH papers online, and read their abstracts.The MINIMUM is 3.7 milliJ/cm^2, or 3700 microJ / cm^2.But it is better to have higher. Another estimate in that abstract is showing 10.6 milliJ/cm^2, or 10600 microJ/cm^2.A good reading for a UVC light sanitizer device is 100 micro-Watt / cm^2. A new, mercury-based bulb with about a 10W power source will deliver 100 micro-Watt / cm^2 about 3-5 inches under the light ON ALL spots.So, how do we translate the 100 micro-Watt / cm^2 to needed 3700 microJ / cm^2?Easy: one Joule is one Watt-Second.Well, we need 37 seconds of exposure. Most UVC sanitizers ask you to run for, e.g., 5 minutes.5 minutes = 300 seconds, and 300 seconds with 100 microWatt / cm^2 equals 30,000 micro-J/cm^2.As you can see, a good UVC sanitizer that delivers at least 100 microWatt / cm^2 on all spots under the light, operated for 3 minutes, will deliver 30,000 micro-J/cm^2, which is MORE than enough to kill the Corona.For the Flu, you need more. Probably closer to 8-10 minutes.To kill bacteria? You need even more, like 30 minutes.Remember: that is a device that delivers 100 microW/cm^2 to all spots!Now, on to measuring our little Nextstar device.When I point one of the "W" lights to my UVC meter sensor, I see exactly 0 microWatt / cm^2 on the meter.ZERO!When I point one of the "Y" lights to my UVC meter sensor, I see 10-15 microWatt / cm^2 on the meter.At 15 microWatt / cm^2, you probably need at least 250 seconds of exposure (4 minutes) to reach 3,700 microJ/cm^2.But remember, this needs to be delivered to ALL spots. If you have something, like a phone which is say, 10cm X 20cm, then you need to hold the wand steady on one spot for 4 minutes. Then move about 1 inch, and hold it for another 4 minutes. And then keep doing it probably 5-10 times.And at the end, you get MINIMAL UVC exposure to kill the corona. May as well take a 15 cent alcohol sanitizing wipe, and wipe your phone. It will be sterile in 30 seconds.In short, this device does not work.In case you are wondering about the "Y" and "W" lights. The little piece of paper that came with the device states:"Y" -> LED bead wavelength 275 nm (count 4)"W" -> LED bead wavelength 400 nm (count 6)Again, 400 nm is NOT UVC. It is UVA. And it does not work to kill virus or bacteria.So, with this device, you only get 4 very weak bulbs, and 6 non-working bulbs.Attaching two pics:- showing the paper insert that came with the wand, showing that only 4 bulbs / beads are UVC- showing the UVC reading of 10 microW / cm^2 under the "Y" light

It is a very substantial sized sanitizer, with a nice cloth case. Very well made.
