I've done a few hundred cases of different calibers, I haven't had it all that long,I'm definitely am not a high volume user, But I do obscure calibers that very few people shoot, Many with rims, That's why this annealer made the most sense to me, It does rimmed cartridges very well and you don't need to buy collets, Wheels or inserts. I used to use a bench source, But it doesn't really spin the cartridges very good. And it takes up too much space, And it uses more than one torch if you want to work the best. The EP was just the best fit for me, I considered a few different machines. If something were to break, It wouldn't be too hard to fix it, The guy who makes these actually has a video showing you how to make one yourself, The parts are not expensive and are not hard to find. I'm not too worried about it.
