extremely fast delivery !!! compact products. not too small, not too large, easy to store, seemingly easy to use. think it is good that the extinguisher is suitable for three common household fire classes. 18 sec. Spray time ... I think that's enough for fires resulting in any case. the functionality of course I still (and hopefully never) not tested. something negative: Date Stamp sometime in 2014. Two annual prescribed examination I must therefore leave even consider next year. So in about a year. the costs of course.
