I am very pleased with the look, size, price and function of these candles. I bought 3 packs of 2 and out of 6 candles - 2 did not work.  I went on line and planned to buy and return a pack but was instructed to order another pack but not to return the pack that didn't work.  Within days I received my new lights which worked perfectly.  I would highly recommend these candles as well as shopping with this company.  They back their products and no hassle with customer service.  They are fast and honest!
