I purchased a solar sensor light from Coopers in June of 2013 and it failed in September of 2014. It was out of their 12 month guarantee but I purchased another in the following month. February 2015 and this one has failed also. I asked for a refund but was told that under the terms of their guarantee they would only issue a replacement. At first I thought I would accept this but 10 days on I am still waiting to hear from them. I have now changed my mind and have demanded a refund as under the trades description act if a product is faulty one is entitled to a full refund. All I get from them though is an automated reply saying that they are experiencing a high level of emails and phone calls. Try to ring customer services and it's constantly engaged. I posted a review on their website a week ago and so far they haven't published it. Seems they only show those that show them in a good light, (no pun on light intended!) I wouldn't but from these people again.
