Honestly, the amount of useless sh*t I've bought from Amazon recently beggars belief. Firstly, there was the ultrasonic rodent repeller that doesn't repel rodents, the trail camera that does capture things moving right in front of it, the rodent repeller balls that the rats just wander up to and sniff and the radiator key which fits so poorly it'll probably round off the bleed valve. Enough is enough!!!!
