You should give a product a low score because YOU ordered the wrong bushing. These are obviously the small cone bushing and aren't even being sold in the long board bushing section so that should give you a clue on the size of them. The official site has more info on taller and different shapes as well as their best applications.
Now, for my review.
I had gone with my stock indies bushing for about 3 or 4 months now but as soon as the temperatures started hitting 90+ they actually melted after an hour of skating. So I just went to my local skateshop and picked up a pair of Do-dohs. After a day of skating they were already busting out of the sides and shredding around all the edges. I skate with fairly loose trucks and definitely don't crank down on them so the bushing were obviously the problem.
I went to get some Bones bushing with the plastic on top but a buddy of mine who barely skates has gone threw 2 pair in a month or so. I knew they wouldn't last me.
So I bought a pair of these and boy am I completely satisfied with the purchase. They're cheaper then other brand alternatives, withstand heat and very hard skating. They snap back into place very fast with takes some getting used to but they make my skating just so much more satisfying. I don't know why more people skate these.
One thing I noticed (Might not be the same for other people)
Is the hardness is different from how other brands list them and I'd recommend going a bit softer than if you were buying another brands bushing previously.
