Letter Lights M - Illuminated Decorative White Wooden Letters with Lights - Lumiletters M

I decided on this light up letter M even though it was slightly more expensive as it had a switch on the side to enable it to turn on/off easily. It would have been good if the switch was white, but the black isn't too intrusive and the switch is towards the back by the wall. The lights are nice and bright but I have found the lights sometimes flicker a little as they are switched on and off - not sure if its a connection issue. Maybe just the LEDs warming up? Height is 22.5cm and the width of the M is 15.5cm, and it has a nice chunky depth of 4.5cm. From the pictures I wasn't sure if there was a plastic cover over the lightbulbs but I am pleased that there isn't, although it may get dusty.The main body is made from white painted composite wood. The product has a small CE label stuck to the back, and is labelled as Made in China and has a batchcode. It seems the bulbs can't be replaced, and the leaflet with it advises that if you use 2x new AA batteries that the lights should work continuously for approx 300 hours. I am not sure how long the bulbs will last.
