The lights will stop working for no reason. We ordered 3 sets which were fine then 1 set just stopped working for no reason at all (they have been on the fence for around 2 years). Contacted the Company and they replaced the set. 2 weeks later another set stopped working (again for no reason) now they are refusing to replace as purchased more than 2 years ago. Clearly not as hardwearing as advertised. We have spent alot of money on these in the hope they would last a long time but clearly not. Save your money and go elsewhere as they will stop working after a couple of years. To have 2 out of 3 sets to stop working a few weeks apart shows they have an expiry date and are not fit for purpose.
