I've taken a number of mice apart and haven't broken anything yet. However, I'm not familiar with the construction of your specific mouse, so I don't want to say they're all easy. I'd say give it a try and stop if it's not clear how something comes apart. If you're nervous about doing this, call them back and tell them that you need advice specific to your product.

Has your son ever tried these mice? They are terrific, espeically the side buttons, flipping back through websites is nothing for me. My scroll bar is so fast even at 800 DPI...its unubelievable...and when I forget to put it in the charger...do I ever hate using the corded mouse until it recharges...everthing is just so easy even for mundane everyday web-browsing. As far as the dents in the MX518...that's where your fingers go and it allows a plyable left and right clicking, its like a mylar type of thing...he doesn't want any dents or lights? Low battery indicator is out? I wish that other MX1000 owner was still here...I've never make a mistake with the side buttons. In the beginning, I hit them a few times by mistake...its called learning, but not once in the last year and a half. Every time my cousin comes over here to play a game, and I tell him to left click ...he always clicks the wheel...he keeps looking for lines to tell him where right and left are. Then he gets used to the idea there are no visible left or right clicking lines, its the entire left or entire right side of the mouse whereever your fingers are comfortable. As far as the lights...they are LED lights and barely noticeable. That one poster said on the MX610 you can turn off the mail indicator ... they are like pinpricks of light...I forget to look at my battery indicators They are not that visible.. The Diamondback Plasma they are more visible...its an art thing and because they are LED they don't use much, if any, extra electricity. Why is your son insisting on archaic mice? Have you watched the little movie presentation? On the link below click on "Product Tour". You can turn features on or off with the software. The hardest thing to get used to is the size. They are larger, they require a bigger mouse pad, and lasers do better on flat light colored surfaces...but lasers will track fairly accurately on any surface. Are they ever sensitive to the slightest movement...but you get used to it...real quick. Instead of wide swings its a flick of your wrist. And believe it or not you even get used to holding the mouse without ever touching the buttons. The only drawback is the 2.4Ghz frequency and wireless routing...the one poster said even with that there was no interference with the mouse's performance...If you don't have a wireless router ...it might be a blast to learn with.

My work keyboard is this one. Work paid for it, so beware the price! I can't say enough good things about it, but mostly, my hands and wrists don't hurt any more. But I use it all day long every day, batteries rarely need replacing. Not only is the keyboard ergonomically split, it's raised. Ah. And the mouse, well, I'll never use another tiny mouse again. It's shaped like a ball and my hands don't feel like I've been griping chopsticks all day long any more. I love it.
