Excellent quality, quite more light weight than I thought... size is perfect and the use is just very convenient.
The only possible drawback I can think of is the type of battery which might get difficult to get a hold on while touring or something alike, but, it is really small and lightweight therefore a spare one can always be in within the peli/backpack.
BUY IT. I DO NOT THINK YOU WILL REGRET THE WAIT NOR THE EXPENSE. Cheers!
