I got one last Christmas and it is a massive time saver to not have to weigh out individual charges, then trickle the powder to make weight. Love mine. I can load up larger lots for the range in so much less time.

I had a part go missing on my RCBS priming tool and they sent out a replacement immediately at no cost, so I would rate my one customer service experience as excellent.

As to the fluorescent light question above, any kind of magnetic or electrical field (including static -- see plastic loading blocks) has the potential to interfere with a digital scale. I have fluorescent lights high on the ceiling in the garage with no noticeable issue. I imagine these items would have to be close to the scale to possibly cause an issue. I had read about this somewhere, but I have never experienced it firsthand, thankfully.
