Bought to populate LED ball table lamps so (after the original LED has failed), the installation was designed as a not particularly difficult. However, but two factors disturb the fun. First, the extremely brittle plastic that difficulty and gently "rework" can and the fact that you have to rework at all because of a total of 4 tested LED candle lamps from different manufacturers 3 did not work because the "plastic stem" of the thread above is too long and the LED lamp abuts at the top before electrical contact is made. Is only due to the low price that barely 3 star - the seller delivers fast and in good packaging, however - there is nothing to complain about.
