which fits?

Which battery, which bag, what size, how many. Look it up, then buy the right one once.

Contents

The small decisions before you buy something ordinary.

Which battery goes in the car key. Which bag the hoover takes. How many lights a six-foot tree wants before it looks like a tree and not a lamppost in a hedge. Nobody needs a review for any of that. You need the answer, the number, the code on the packet, and then you need to buy the thing once and get on with your life. That is what these sheets are for. Each one is a question, a way of working out the answer, and the answer. Pick yours.
