ive just dismantled my lavabox m few days back, it really is just the 2 long screws keeping it tgt. after removing the 2 long screw at the back of battery, u can actually grab the negative and positive "post" and pull outwards to take out the battery compartment, revealing the dna board. do remember to pull outwards gently as the cables connected to both post is kinda short. there is no hidden screw or clip holding it, just tightly fitted in there. i can post a few pics if anyone here need it.
That's good to hear. I don't need to disassemble mine, but I would have been a little annoyed if it was manufactured in such a way that it could not have been taken apart.
