I have bought a similar one and it does not withstand time very well. The brightness intensity is not recommended. The construction is quite good, but the lighting is not...

For its price, it's fine!
Its battery is noname and of course, the mAh it claims to have has no relation to reality, but it lasts quite a bit.
On the plus side, it comes with chargers for every use.

Because I had bought another similar one from China, this one is of worse quality. Of course, I had bought the one from China with a little more money. Generally, though, it is good and quite bright. Now, as for whether it can withstand falls and water, I don't know...
