i have a lidl one too, i bought one last year and it lasted well until i left it stuck(magnetic) to the bottom of a car on a test drive. i think it came off at around 60mph but survived pretty well, it just cracked the lense near the handle and carried on working for a few months but because of the crack flexed a lot and eventually broke the connections. i went down to Lidl yesterday to get some workshop tea/coffee supplies and was pleased to see they have them back in agian so grabbed a new one :)
Just been to Lidl for some milk and bought a rechargable LED lamp while I was there.
