The Brick Fan
“Overall, The Big Bang Theory (21302) set is a nice little vignette set that resembles the real-life counterpart very well. The only thing that’s sort of out of place is the setting of the minifigures on the box and in the official images. The attention to a lot of the little... More details throughout the set is what makes it a great one.”

Eurobricks
“The quality of the box, manual, and set are all really excellent. It's exactly what you'd expect an Ideas set based on the BIg Bang Theory would be like.”

Rebrickable
“This is a set almost entirely targeted to fans of the show. For them, the set will surely appeal mainly due to the high quality minifigs, and they'll be enthralled by the highly curated reconstruction of all details from the show. It's a great display piece and a perfect... More "geek" gift for your friends who are fan of the show but not (yet) of Lego.”

About Ideas Licensed

Licensed is where LEGO Ideas sets based on films, TV series, games, music and brands are filed. Each began as a fan design that reached 10,000 supporters on the Ideas website before LEGO reviewed it, and the fan whose design is made gets a share of the sales. Licensed ideas are harder to get made, because LEGO also needs an agreement with the owner, and many popular projects have stopped at that step.

Licensed was introduced in 2012 and currently consists of 42 sets. As of today, 21348 Dungeons & Dragons Red Dragon's Tale is the most valuable Licensed set with an estimated new/factory sealed value of $524.

Ideas Licensed The Big Bang Theory set 21302 was released on August 2, 2015, retailing for $60, it has since been retired. New, unopened sets are valued at $293, used ones can be found for $162.
