Don't last long at all, may be fakes
on 28 November 2010
These may be a fraction of shop prices, but I suspect they may be fake. I use these in cycle lights and 'genuine' ones last me two winters.
I purchased these at the beginning of November 2010, and by the end of the month all are spent, each pair lasting between two days and two weeks. Not quite the same as two years!
