I recommend the AIRTHINGS radon detector. On sale on Amazon for about half the price of the one you linked above and works great. You leave it in a room for however long you want to test for, and then you can reset it and do another room if you want. Much better than the mail-in tests imo.

EDIT: same one linked by Dentoman
