He he. I'm glad you posted, Harleygold. I haven't been able to get mine open to look at the batteries! I hope somebody has already tried that. I am hesitant to pry it...😕
It is very fragile, or feels that way. You just need to pull the black slider back and then replace the batteries. From there you would press firmly down near the black slider until it clicks. I have opened mine three times now with no issue.
