Exaggerated Brightness
As usual, the brightness is far exaggerated and will never reach the promised 5000lm. Compared to my 1600lm flashlight its more like 900lm, still bright enough for certain tasks.I have one of this always in my car and others in each room of my house in case the power goes out. I can not say anything about durability though as I only have it for a couple of weeks.

Great flashlight in every work environment
I bought this item cause I always loose flashlights. These are handy enough to fit in the pants pocket without dragging them down as it is with larger lights. I use 18650 Batteries but can also use 3 AAA batteries as the adapter is included with is a big plus.
The brightness advertised as 20000 Lumen I find too high, 2000 Lumen is more likely the case with these lights. So far I had not yet any negative experience with the Ultrafire flashlights.
They are very durable in a daily work environment (as in construction or service work).

It does what it is supposed...
The write speed is kinda slow but that was not my target. I am using these to install different Windows Versions and thats where I need them to shine. The read speed is appropriate for an USB2 stick so I can not complain. It works for the purpose I intended them to use.
