If I was simply reviewing the charger I would have given 5 stars. However, I'm reviewing the whole process of the sale including the advertising which is extremely misleading. The picture shows the charger with 4 batteries and that's what I expected to receive. Not so; the charger arrived without the batteries shown so be aware that you are only buying the charger and not the charger and 4 batteries. Very naughty piece of advertising and I am amazed that Amazon have allowed it.
We have squirrels in our loft and, after buying a trap that turned out to be just an expensive way of feeding squirrels, we decided to try this. We have now had it for three weeks and it has not made the slightest difference. Total waste of time and money. Can't even think why it would get one star.
