It may well be true that you get what you pay for when purchasing non-original items. My Canon camera is already advising me to change the battery pack & I only use it intermittently. I will try to source an original battery to replace this one & realise I will pay alot more but should achieve good battery life.
This product is perfect for when you are travelling or going on holiday. Offers total protection from the usual bumps & scuffs that the i-pod suffers with. Delivery was also excellent as it came just 24 hours after ordering.
