They pop out in the locking stage. Many people have tried and no one can get them to go in without a struggle (well, my installer's the only one who could get them to go in). Cali bamboo doesn't think it's a product failure.
They don't think a month is long enough for acclimatization and I wish I knew about this before I bought the floors and spoke with their sales rep for hawaii. I thought I was dealing with a good company but it turns out they just wanted the sale. I just read some experiences people had with them on some website about ripoffs and what those people say doesn't surprise me at all. I might just have to add to it but want to believe those boards will straighten like they say or the company will step up and take responsibility. Maybe too optimistic but I don't like negativity unless its the truth and to protect others from headache and wasting money, time and energy.
