Mir are mainly following things are important: quality, features, function and price.
Quality:
The quality suits. Black aluminum housing, meticulously crafted, and the thread. The lamp fits comfortably in your hand. Here you'll find nothing to complain about. Even a brief illustrated guide (leaflet) in halfway understandable, the German language is attached.
Features:
The lamp can be operated with 3 little AAA batteries / accumulators or with a 18650 Li-ion battery. Although there are no batteries, but fortunately both a 18650 battery and a matching charger for included respect!
Function:
Adjustable are three different brightness levels and strobe and SOS. Both ON / OFF and the various brightness levels are controlled via the colored pressure switch on the end cap of the lamp. The flash coverage can be achieved by simple assembly and pushing apart the handle continuously regulate (see product photo # 2).
Brightness and range:
That LED flashlights are very bright and usually have a relatively large lighting range, is now commonplace. Also on the product of Alldaymall this is true. What has surprised me a little, was the color of light. My Compare lamp emits clearly knows here, however, the color is slightly purplish. I feel this is noticed only in direct comparison, but maybe that's for the odd indeed an important feature.
Price-performance ratio:
For currently about 16 EUR I think it is a really good offer, especially when the battery charger together with reckons.
Conclusion:
Overall, I vacillate between 4 (due to the light color tone) and 5 stars (because of the inexpensive complete package), on the current price level with a tendency towards the latter.
