Every episode in one boxset, it even includes the pilot episode which runs for about 90 minutes. It's interesting to see Face in the pilot episode who is played by Tim Dunigan, who was later sacked and replaced by Dirk Benedict, as Dunigan looked too young for the part.
There was some confusion about how many episodes had been made, having done some research online, this boxset does include every episode. Some episodes came in 2 parts on TV, but have been made into 1 episode on DVD. Don't worry, every episode is in there!
The DVDs come in slim cases, the storage box is a bit flimsy, but I wasn't too bothered about it. A brilliant boxset for the price, 10 out of 10.
