An important warning for anyone buying loose Transformers equipped with Electronics, (ie. batteries): I found a loose, (but complete), Nemesis Breaker for $15, for a gift for a kid in my family, since he is equipped with a sound function, I tested it. It behaved wonky, so I went to change the batteries. When I opened the battery compartment, to my horror I discovered the old batteries, (one of them in particular) had leaked pretty badly. Thankfully, I work with electronics so I know how to deal with a gummed up battery compartment. That said, a lot of people buying Transformers probably don't have electronics experience like I do, (though I'm sure I'm not the only one.) I cannot emphasize enough, that this is a DANGEROUS phenomenon for a child to discover. (I learned this the hard way when I was a kid, but thankfully no one was seriously injured in that incident.) Battery leakage BURNS. PLEASE make sure you double-check the electronics in any loose Transformer you're giving as a gift this Christmas, (and check any boxed oldie your kids receive on Christmas), and be safe when cleaning out battery leaks.
