Save Your Money
To be fair I have been spoiled by Bath & Body Works Shower Steamers, and they set the standard by which I judge these steamers.  I only try these other brands because the B&BW ones are rare as hen's teeth here in West Texas.  Besides the flimsy plastic container these come in, I could discern no scent in the blocks nor in the shower.  I tried them on the floor in the front corner where I usually put such things - with no success.  I next tried the shelf which is located in the same corner just below shoulder height.  Even after putting a stream of hot water on them - they produced no scent.
