Got 2 boxes and was expecting maybe one duplicate, but I ended up with 3- the planet deskmat, skylight horizon keycaps, and Everglide linears. Maybe get one for the novelty, but don't get 2 planning on getting different stuff.
EDIT:
Contacted support and they sent over another box. No duplicates on the 3rd box. Bumped the review up to 3 stars thanks to the helpfulness of the support team, but still wouldn't recommend getting more than one box.
aintnohoebagI had the same thing happen to me with the duplicates. A total of 3 sets of duplicates in two boxes. Crazy hit rate considering the variety of items that could have been in the mystery boxes.
