COLORFUL LIGHTS FAIL TO WORK
Reviewed in the United States on June 19, 2019
I ordered three ten-packs of lights from MJMIX—one bright white, one yellow, and one colorful (mixed colors). White and yellow worked fine—but the mixed color ones work when switched on, but after a half-hour or so, all but the 4 blue ones go out. I would suggest you find another vendor for the colorful ones although I've been happy with white and yellow from MJMIX.
Unfortunately, I didn't discover the failures until I'd given six of them as gifts and recipients began to mention the failures.
