If size is one of the most important issues for you, you will love the TinyCycler. Guaranteed high performance like the Micro in the world's smallest size and weight. Only lacking the Battery Gauge but does have Low Battery Warning like our #VHMC MiniCycler.

If you have a flash that will accept a connecting cable that Lumedyne makes it will work. This is an "assist" battery. I have Nikon SB 800 flashes that have a socket where you plug in a high voltage battery to recyle faster. This battery is awesome. I have fired more that 1000 flashes at weddings with no slow down. The flash still needs the in-flash batteries to power the other functions other than recycle. Best bang for the buck!
I was disappointed that I received a defective battery. Lumedyne did fix it under warranty but I still had to spend $15 for postage & insurance.
