I bought two sets of outdoor solar lights just before Christmas. Half of each set didn't work so I emailed about the problem. I received an email back asking me to try them with a battery! These are solar lights so how I was supposed to try with a battery is beyond me. I rang the next day and Mat said he would send replacements. They arrived and again half don't work. I put them outside in the hope 8-10 hours of daylight would let them charge. It is now over a week since they have been outside and now non of them work. That's £18 down the drain. Useless they are cheap lights and I wouldn't buy anything from Lights4fun again.
