I've never used branded trugs, but I buy very similar ones made from recycled rubber from the builders merchants. They are virtually indestructable!
We use them for carrying concrete, one person each side - they really are that strong! I also use them for rock picking, laundry, hauling compost, anything really. I love that you can carry lighter things in one hand and the same thing is strong enough for the toughest, heaviest jobs. We have some that are ten years old and have been outside in the summer sun and are still as good as new. I have one I drilled holes in the bottom of so I can rinse stuff in it. I think they cost €3.50 each so they are very affordable, too.
Here's my laundry set-up using two trugs.
