I've owned and used six of these for over 20 years, shooting 3 to 6 days a week. They helped earn a small fortune and I don't remember a failure.

Im not a "verified Buyer" because I bought mine to Calumet Photographic 32 years ago...I have travelled, worked in smoky , dirty manufacturing factories, outdoors, I have rented it to friends for days, and weeks, and early this year I took this photo. There is no better Light system than Speedotron. I give them 10 stars
