flameless candles similar to luminara

fenwicks and amazon are selling a luminara look alike flameless candle from a company called premier. they are all wax and have the similar dip at the front. the glow is very good and the flame is very similar to the luminara spinning and flickering. the light is led. it takes 2 AA batteries and has a timer. the medium candles cost £16 and is 18cm. fenwicks had a 20% off evening.

i wanted to buy the pacific lights candle but would have set me back around £50 inc postage.

heres a link this is cheaper than fenwicks but its the same candle http://www.amazon.co.uk/dp/B00E8CLVBS/?tag=shoppingcom03-21

How long do the batteries last?
Just looked at Amazon and a reviewer has said 2 weeks on timer. I use rechargeables so I reckon around 8 days.

not sure as i have just bought them tbh..most of the reviews were positive. i suspect it depends on the batteries you use. alkaline are supposed to be better. also duracell are supposed to be good
