What I want to know is the actual user opinions on having the the brightness buttons on the back vs on the side. I'm thinking of getting the EXPS model due to the fact I thought the buttons on back may be a bit tougher to use rather than the side buttons. Whatcha all think?
I've spent some time with a 517, and I found the side mounted buttons troublesome to manipulate. This was especially true when using gloved fingers and trying to turn the unit off. I think it would be better if EOTech used the same sized buttons they do on the regular units, but only shifted to the side. I'm not sure why they went with a smaller button size, especially considering they're already recessed. Doesn't make any sense.
