i just A Dranzer GT today in the mail

And like 10 battles later

the base exploded
i manage to find all parts and springs, and stuff

Now everytime I put bladeblade together
A few battles later it explodes.

So i want to buy Dranzer GT bladebase

Why not try asking for a replacment? I've had mine fore years, and it's probably been used in 20 battles(not alot, but double your count), and I haven't had a single problem.
