The device fits comfortably in your hand and has a sufficiently long cable. Unfortunately, it's quite loud and in fact it must also cool again (to 30-50 flashes). To larger areas (legs, back, etc.) to handle the device in my eyes not suitable! Only because of the small "window".
I also believe the first Katusche was empty after less than 1000 lightning ... This is of course extremely expensive at the price of 20 euros !!! ;-(
Generally speaking, the device fulfills its purpose but well and probably I would buy me again!
