Hi all,
I bought the Manker U21. I keep it as an emergency light and have used it only a few times, maybe 20 times at most. I did indeed outshine my other lights distance wise. Very impressive distance. BUT - It has stopped working. When I activate the switch, the little square emitter flickers dimly, in a random pattern. I tried freshly charged batteries and have tried every switch combination - fast press, slow press, long press, a series of short or long presses.
I can not find any customer support number in the USA.
I emailed them at
[email protected] on April 5 and as yet have received NO RESPONSE.
My conclusion: Faulty product. Poor/no customer service.
