My main issue is that I had 3-4 boxes that just never came. I was also effectively ghosted by support after being told that a holiday box that never came would be sent again after the holidays. It never came and they stopped responding to my emails. From what I can tell, I never received at least 3 boxes.
The good news is that I don't think any of these were from a subscription, though with one of the potentially missing items being a mystery box it's hard to tell. Rather, I bought one-off Christmas stocking and mystery surprise boxes that were the issue. The boxes for the subscriptions all have fun themes and are generally high-quality products. I prefer the lifestyle items to the book/tea subscription, personally. Occasionally, the boxes feel a little sparse, but nothing is "cheap" or of a poor quality.
I was so looking forward to the arrival of this box. However, I am very disappointed with the contents. I am not a Harry Potter fan, sorry. And it's seems to be a box curated for a child. I don't know what to do with the contents.
