Entry Size: Is the opening which must be the size of your balls and your penis together. Please refer to "How To Measure" page in the help center tab of our website. 

Chamber Size: Is usually a fixed size. This part should be large enough to have room for you to grow and expand (but not so big that it is hard to carry), to build good suction and not too small to get pinched. The best is to let your desire do the job.
