I agree with BigMacFu, see if you can return the humi. Even if it was at 100% humidity and 90 degrees, it should not have warped that quickly. That tells me that either the company gave you a used humi or they got a few years ago and it sat it a storage locker or some other uncontrolled environment for a while before it was shipped to you. If the company has any type of credibility or class, they should gladly take it back and replace it with one of a better quality. Call them, and explain the problem...be nice about it and you should get far. If you don't get anywhere being nice, then it is time to do a little ass whipping and create a post on here and let everyone know where not to buy anything.
