Bought in July, and used basically for fetching the shopping.
It arrived when expected, and fitted fine, and is secure once fitted. There are three large containers - one each side and on top - and a small pocket on each side for papers, and two rear pockets shaped for bottles. The zips are fitted so they won't get opened when in use by dragging on things. Its been secure and served its purpose. On the one wet day, the shopping did not get wet.
However there has two issues.
First - how to get the shopping from the supermarket to the bike? I tried taking the panniers off and into the supermarket, loading them at the checkout, and then carrying them to the bike. Not good. The pannier is hard to fix onto the bike when full! If I use the store's carriers this is wasteful. If I take my own bags, they have to be taken home on the bike as well, limiting capacity.
Second, and most disappointing is that the horizontal seam to the top section has split. As it gets worse, the top section will shed its contents. This is after 5 months of approx weekly use. The Supermarket is just under 2 miles away, and I have not strained it, so the use has not been heavy. OK, it is an inexpensive pannier, but I am rather disappointed.
