The picture mislead me and I thought the box was supplied. My goof though for not reading. Anyway after getting a decent box the installation was very easy. I sterilized it and used it for the first time last night. First time using Agar dishes period.. am sure the box performed perfectly and w a s easy to use. I recommend getting the largest box you can 66qt or larger and transparent. Everything was easy to use and provided I didn't screw up all should go well!! Fingers crossed!!!!
