Value is definitely 5 stars. What you receive for the price with this kit is outstanding. The only reason I gave this kit 4 stars vs. 5 is because the directions recommend cutting a 1 x 1 square as a refill hole. This is done by heating up the end of a (preferably old) utility knife with a lighter and then cutting the hole by melting your way through the plastic. It’s quite easy actually. What I did was to cut out a 1′ x 1′ square of a label and stick it in place and then cut around it with my utility knife.
