The box, containing the strobe, will be marked with a sticker 'FIRMWARE UPDATE V1.4'
I don't know what negative reports you have had a about the Canon S100, but my friend and I both have one and have been very pleased. We just returned from Truk Lagoon. He got some great photos using dual YsD1 strobes and his Canon S100 in an FIX housing. I was using a new Sony Rx 100 in a Nauticam housing with a single YS-D1 and was very pleased with the strobe.
