Riakrum 12 Pieces Blacklight Flashlights LED UV Handheld Mini Light Flashlight Small Portable Detector 395nm 9 LED Light, Not Included Battery(Black)

Flashlights worked well

Two of the flashlights have minor defects that prevent them from working. Because they were purchased to be sent as a free gift to my subscribers I've sent the 10/12 that worked and will turn the remaning 2/12 over to my resident experimenter. LOL He'll probably part them out for pieces for another project. I am sad that there's no way to report this except to give a review, as the other 10 are really remarkable for the price. :D

I got these to go with my blacklight products for customers. Works great and havent gotten any complaints. Nice easy small light.

I bought 2 sets of 12 to have a class set for my classroom. I even purchased 100 AAA batteries to go with them. Each one requires three AAA batteries. Not a cheap purchase by far...I went to start setting them up for my blow in the dark activity and NONE OF THEM WORKED!!!! I knew it was too cheap to be true.

I would NOT purchase again. They worked. So I can’t give them fewer than three stars for that… but they did not come with batteries, so when I thought I was ordering the cheapest ones, I didn’t factor that in. Putting the batteries in was excruciating. If fingernails on a chalkboard bother you, you need to ask someone else to put the batteries in because it was way worse that that twisting the tips off. 😭 I also got several metal slivers in my hands that were very painful and hard to get out.

The media could not be loaded.

Cheap product not worth buying

The spring on the button was temperamental. I had to adjust that. The treads were a bit difficult. The battery was difficult to put in the flashlight. It is bright enough to light up neon at close distance,. So it does what I need it to do.
