Tbh the "cheaper Chinese ones" have been more robust, versatile and reliable than three other well known brands I tried - each of which have failed to do what they promised or were meant to do.
These I have found o good, I use them at home and take one on holiday for emergencies.
I am ordering an 800 lumen variable flood-/spot and a air of batteries -same as my existing- for £20 delivered and I have with in it doing what I want and need.
Yes, there are some really naff Chinese items out there, but never been disappointed by this supplier.
There again I may be he exception?
