This is a good size and quality for the price. I too wanted it to store birdseed and it does the job perfectly. When I recently moved my garden shed I contemplated emptying the bin of seed before moving it, to avoid strain on the handles. Before I had time to do this, I discovered my partner had already lifted it out of the shed while still full, with no ill effects on the bin itself.
I had priced alternatives in my local DIY superstore first. All the cheaper versions were a smaller capacity than this one from Amazon so I think the price is good, and the delivery charge justifiable for the convenience.
