I recently bought an RPL300 from Pseudo and I just want you all to know that it and he are BADASS! I only know what i read here about lasers, but a friend told me(after he saw and touched it) that this RPL from Pseudo is identicle to the Opto product and I think he said "AWESOME". I'm not saying this to take anything from Jack and Opto, but only to settle some uncertanties. I think they know each other pretty well,and can't tell if either is trying to compete with the other. Jack seems to have a longer warrantee...whatever. I hope nobody is bothered either way...it all seems kinda touchy, an i don't wanna stir nothin up. It's just a real nice laser.AWESOME I mean!PS None of this means I don't like my Aries!
